This will typically occur with deprecated or non-FIPS cipher algorithms (cipher-algo=blowfish/bf, twofish, cast5, or 3des). By default, pgcrypto will now fail to decrypt any messages that were affected in this way. To allow retrieval of such data, a new option ignore-cipher-failure has been added to pgp_pub_decrypt() and pgp_sym_decrypt(). Setting ignore-cipher-failure=1 will restore their previous behavior, allowing the faulty encryption wrapper to be stripped off: pgp_sym_decrypt(encrypted_column, any key, 'ignore-cipher-failure=1') Once the affected messages are identified and stripped of their wrappers, they can then be re-encrypted with a modern algorithm. It is important however that the behavior of OpenSSL be the same as it was when the faulty messages were created: if the set of unsupported algorithms is not the same, this approach will not work.

在假定支持排序规则的类型上的等值条件意味着唯一性之前，检查是否存在非确定性排序规则（Richard Guo）§ §

\n

许多规划器优化都会假定，例如，如果 x 上存在唯一索引，则最多只有一个表行能满足 WHERE x = 'abc'。不过，如果该索引和 WHERE 子句附加了不同的排序规则，一般来说这个结论是不安全的。当两个排序规则都是确定性排序规则时这是安全的，因为该属性本质上要求两个字符串相等就意味着逐位相等。但非确定性排序规则并不如此，因此如果 WHERE 子句或索引任一方具有非确定性排序规则，基于唯一匹配假设进行优化就可能给出错误的查询结果。

将 NOTIFY 消息处理期间发生的错误升级为 FATAL，即关闭连接（Heikki Linnakangas）§

\n

以前，如果后端在吸收 NOTIFY 消息时遇到错误，它会跳过该消息，向客户端报告错误，然后继续运行。但这种行为存在很多问题。一个主要问题是，客户端没有好的方法来知道通知丢失了，更无法知道通知的内容是什么。根据应用逻辑的不同，错过一条通知可能导致应用程序卡在等待状态。此外，剩余的消息在有人发送新的 NOTIFY 之前不会被处理。

修复在有多个扫描条件的 GIN 索引扫描中可能出现的无限循环（Tom Lane）§

GIN 可以处理能够拒绝不匹配条目但不适用于搜索相关条目的扫描条件，例如 tsquery 子句如 !term。但此类条件不能排在扫描条件数组的第一个位置。代码在所有情况下都未能确保这一点，导致包含此类条件与正常条件混合的查询可能根据查询中条件给出的顺序不同而正常工作或不工作。

避免从流式传输切换到归档 WAL 源时不必要的 WAL 接收进程关闭（Xuneng Zhou）§

加强规划器估算函数中的安全检查（Dean Rasheed）§

\n

针对 CVE-2017-7484 的修复及后续修复，旨在防止泄漏函数被应用于调用用户无权读取的列的统计数据。在该保护措施中发现了两个漏洞。其中一个漏洞适用于分区和继承层次结构，其中表上的 RLS 策略应当限制对统计数据的访问，但实际上并未限制。

\n

另一个漏洞适用于查询通过视图访问表的情况，其中视图所有者有权读取底层表，但调用用户没有视图的权限。视图所有者的权限满足了安全检查，而泄漏函数会在我们检查调用用户对视图的权限之前就被应用于底层表的统计数据。此问题已通过在规划开始时对视图进行安全检查来修复。这可能会导致权限错误比之前更早发生。

Two gaps in that protection have been found. One gap applies to partitioning and inheritance hierarchies where RLS policies on the tables should restrict access to statistics data, but did not. The other gap applies to cases where the query accesses a table via a view, and the view owner has permissions to read the underlying table but the calling user does not have permissions on the view. The view owner's permissions satisfied the security checks, and the leaky function would get applied to the underlying table's statistics before we check the calling user's permissions on the view. This has been fixed by making security checks on views occur at the start of planning. That might cause permissions failures to occur earlier than before.

防止 pg_dump 脚本被用于攻击执行恢复的用户（Nathan Bossart）§

\n

由于导出/恢复操作通常涉及以超级用户身份运行 SQL 命令，目标数据库安装必须信任源服务器。然而，这并不意味着执行 psql 进行恢复的操作系统用户也需要信任源服务器。这里的风险是，已获得源服务器超级用户级别控制权的攻击者可能会使其生成被解释为 psql 元命令的文本。这将提供对恢复用户自身帐户的 shell 级别访问，独立于对目标数据库的访问。

However, it does not follow that the operating system user who executes psql to perform the restore should have to trust the source server. The risk here is that an attacker who has gained superuser-level control over the source server might be able to cause it to emit text that would be interpreted as psql meta-commands. That would provide shell-level access to the restoring user's own account, independently of access to the target database.

避免在逻辑复制期间重新分发来自其他事务的缓存失效消息（Vignesh C）§

我们上一轮次版本发布中包含了一项修复，确保复制接收进程会响应跨进程缓存失效消息，从而避免它们在执行复制更新时使用过期的系统目录数据。然而，该修复无意中也让这些进程再次重新分发这些消息，导致失效消息数量呈指数级增长，并且常常以内存分配失败告终。现已通过不重新分发收到的消息来修复该问题。

改进 libpq 引用函数的行为（Andres Freund，Tom Lane）§ § §

\n

为 CVE-2025-1094 所做的修改有一个严重的疏忽：PQescapeLiteral() 和 PQescapeIdentifier() 未能遵循其字符串长度参数，而是始终读取到输入字符串的末尾空字符。这导致在调用者打算通过长度参数截断字符串时，输出中包含了不需要的文本。在极端不幸的情况下，可能因读取超出内存末尾而导致崩溃。

\n

此外，修改了所有这些引用函数，使得在检测到无效编码时，仅替换假定字符的第一个字节为无效序列，而不是全部字节。这降低了在调用应用程序对引用后的字符串进行额外处理时出现问题的风险。

This resulted in including unwanted text in the output, if the caller intended to truncate the string via the length parameter.

加强 PQescapeString 及相关函数对无效编码输入字符串的防护（Andres Freund，Noah Misch）§ § § § § §

\n

libpq 提供的数据引用函数现在会完全检查其输入的编码有效性。如果检测到无效字符，会尽可能报告错误。对于缺少错误返回机制的函数，输出字符串会被调整以确保服务器会报告无效编码，并且中间处理不会被恰好匹配单引号、反斜杠等的字节所欺骗。

\n

此变更的目的是防范在使用这些函数对精心构造的输入进行引用时可能发生的 SQL 注入攻击。当结果字符串直接发送到 PostgreSQL 服务器时没有风险（服务器无论如何都会检查编码），但当它通过 psql 或其他客户端代码传递时存在风险。历史上此类代码未仔细审查编码，在许多情况下如果检测到此类问题也不清楚应该怎么做。

\n

此修复仅在数据引用函数、服务器以及任何中间处理对所使用的字符编码达成一致时才有效。插入不可信输入到 SQL 命令中的应用程序应特别注意确保这一点。

\n

不使用这些 libpq 函数而引用不可信输入的应用程序和驱动程序可能面临类似问题的风险。它们应首先确认数据在服务器期望的编码中是有效的。

If invalid characters are detected, they report an error if possible. For the ones that lack an error return convention, the output string is adjusted to ensure that the server will report invalid encoding and no intervening processing will be fooled by bytes that might happen to match single quote, backslash, etc. The purpose of this change is to guard against SQL-injection attacks that are possible if one of these functions is used to quote crafted input. There is no hazard when the resulting string is sent directly to a PostgreSQL server (which would check its encoding anyway), but there is a risk when it is passed through psql or other client-side code. Historically such code has not carefully vetted encoding, and in many cases it's not clear what it should do if it did detect such a problem. This fix is effective only if the data-quoting function, the server, and any intermediate processing agree on the character encoding that's being used. Applications that insert untrusted input into SQL commands should take special care to ensure that that's true. Applications and drivers that quote untrusted input without using these libpq functions may be at risk of similar problems. They should first confirm the data is valid in the encoding expected by the server. The PostgreSQL Project thanks Stephen Fewer for reporting this problem.

将并行工作进程排除在连接权限检查和限制之外（Tom Lane）§

启动并行工作进程时不再检查 datallowconn、rolcanlogin 和 ACL_CONNECT 权限，而是假定领导进程最初通过了类似检查就足够了。这避免了例如当领导进程以缺少登录权限的角色运行时，并行化查询出现意外失败的情况。同样，ReservedConnections、datconnlimit 和 rolconnlimit 限制仅对普通后端执行，且仅计算普通后端的数量来检查是否已达到限制。这些限制旨在防止普通后端过度占用进程槽位——而并行工作进程和其他特殊进程有自己的进程槽池和自己的限制检查。

That does not help vulnerable pre-existing operator families, though, so a band-aid has also been added to DROP OPERATOR FAMILY to prevent failure when dropping a family that has dangling members.", "commit_aliases": ["0e4fa06ba", "1a34cf0f4", "3f9b96217", "531cbd8b7", "5b44a317a", "725d98102", "be5db08ed", "c82003760", "d40191467", "d9d5e1b48", "ec7b89cc5", "faad01835"], "source_commits": ["0e4fa06ba", "d40191467"], "source_entry_id": "15.11/changes/022", "db_id": "852c329ec3909d265b3bad80c3ac798b", "patch_ids": ["135c9629d93bad2ef92966c3a09523c8", "89d8a09d4223474aa10b54f36b93854b"], "statement_hash": "6ab3fdc7d8478fbf69f58ee61e9fa0f8851902d752a14f6b1fbf45071c292356", "relations": [{"rule": 2, "type": "equivalent", "target": "3a292f4b1a44d4abe77ccc4ce2e3f615", "evidence": {"same_day": true, "patch_ids": ["135c9629d93bad2ef92966c3a09523c8", "89d8a09d4223474aa10b54f36b93854b"], "statement_hash": "6ab3fdc7d8478fbf69f58ee61e9fa0f8851902d752a14f6b1fbf45071c292356"}}, {"rule": 2, "type": "equivalent", "target": "b893b83469747828041e23575b6becad", "evidence": {"same_day": true, "patch_ids": ["135c9629d93bad2ef92966c3a09523c8", "89d8a09d4223474aa10b54f36b93854b"], "statement_hash": "6ab3fdc7d8478fbf69f58ee61e9fa0f8851902d752a14f6b1fbf45071c292356"}}, {"rule": 2, "type": "equivalent", "target": "d861457038b8978ee33b63aff90940c4", "evidence": {"same_day": true, "patch_ids": ["135c9629d93bad2ef92966c3a09523c8", "89d8a09d4223474aa10b54f36b93854b"], "statement_hash": "6ab3fdc7d8478fbf69f58ee61e9fa0f8851902d752a14f6b1fbf45071c292356"}}, {"rule": 2, "type": "equivalent", "target": "ffeb4a2fe1782672a84dc4d064b00e4a", "evidence": {"same_day": true, "patch_ids": ["135c9629d93bad2ef92966c3a09523c8", "89d8a09d4223474aa10b54f36b93854b"], "statement_hash": "6ab3fdc7d8478fbf69f58ee61e9fa0f8851902d752a14f6b1fbf45071c292356"}}], "version": "15.11", "category_label": "BUG 修复", "also_in": [], "variants": [], "related_changes": [{"db_id": "b893b83469747828041e23575b6becad", "kind": "equivalent", "version": "17.3", "label": "17.3", "title": "修复操作符族成员操作符或支持函数可能成为悬空引用的情况", "evidence": {"same_day": true, "patch_ids": ["135c9629d93bad2ef92966c3a09523c8", "89d8a09d4223474aa10b54f36b93854b"], "statement_hash": "6ab3fdc7d8478fbf69f58ee61e9fa0f8851902d752a14f6b1fbf45071c292356"}, "url": "/docs/compare/?release=17.3#17.3-c6abed0f8e2bb3a8", "source_url": "/docs/release/17.3/#RELEASE-17-3-CHANGES"}, {"db_id": "d861457038b8978ee33b63aff90940c4", "kind": "equivalent", "version": "16.7", "label": "16.7", "title": "修复操作符族成员操作符或支持函数可能成为悬空引用的情况", "evidence": {"same_day": true, "patch_ids": ["135c9629d93bad2ef92966c3a09523c8", "89d8a09d4223474aa10b54f36b93854b"], "statement_hash": "6ab3fdc7d8478fbf69f58ee61e9fa0f8851902d752a14f6b1fbf45071c292356"}, "url": "/docs/compare/?release=16.7#16.7-c657434a0bda78ba", "source_url": "/docs/release/16.7/#RELEASE-16-7-CHANGES"}, {"db_id": "3a292f4b1a44d4abe77ccc4ce2e3f615", "kind": "equivalent", "version": "14.16", "label": "14.16", "title": "修复操作符族成员操作符或支持函数可能成为悬空引用的情况", "evidence": {"same_day": true, "patch_ids": ["135c9629d93bad2ef92966c3a09523c8", "89d8a09d4223474aa10b54f36b93854b"], "statement_hash": "6ab3fdc7d8478fbf69f58ee61e9fa0f8851902d752a14f6b1fbf45071c292356"}, "url": "/docs/compare/?release=14.16#14.16-59648940f61270ce", "source_url": "/docs/release/14.16/#ZH-AUTO-RELEASE-14-SECT2-14"}, {"db_id": "ffeb4a2fe1782672a84dc4d064b00e4a", "kind": "equivalent", "version": "13.19", "label": "13.19", "title": "修复操作符族成员操作符或支持函数可能成为悬空引用的情况", "evidence": {"same_day": true, "patch_ids": ["135c9629d93bad2ef92966c3a09523c8", "89d8a09d4223474aa10b54f36b93854b"], "statement_hash": "6ab3fdc7d8478fbf69f58ee61e9fa0f8851902d752a14f6b1fbf45071c292356"}, "url": "/docs/compare/?release=13.19#13.19-49d365b591d370b3", "source_url": "/docs/release/13.19/#id-1.11.6.10.6"}]}, {"id": "15.11-4ddb503d2428c1e4", "cves": [], "html": "

确保当 RLS 应用于非顶级表引用时，缓存的执行计划被标记为依赖于调用角色（Nathan Bossart）§

\n

如果查询中的 CTE、子查询、子链接、安全调用者视图或强制类型转换投影引用了具有行级安全策略的表，我们忽略了将结果执行计划标记为可能依赖于执行它的角色。这可能导致同一会话中后续的查询执行使用错误的执行计划，然后返回或隐藏本应被隐藏或返回的行。

使 libpq 丢弃在 SSL 或 GSS 协议协商期间收到的错误消息（Jacob Champion）§

在加密协商完成之前收到的错误消息可能是由中间人注入的，而不是真正的服务器输出。报告该消息会带来各种安全隐患；例如，该消息可能伪造查询结果，粗心的用户可能会误以为是正确的输出。最好的方案似乎是丢弃这类数据，仅依赖 libpq 自身对连接失败的报告。

修复 SET SESSION AUTHORIZATION 与 SET ROLE 之间意外的交互（Tom Lane）§ §

\n

SQL 标准要求 SET SESSION AUTHORIZATION 具有执行 SET ROLE NONE 的副作用。我们对此的实现有缺陷，导致两个设置之间产生了超出预期的交互。值得注意的是，回滚一个执行了 SET SESSION AUTHORIZATION 的事务会将 ROLE 恢复为 NONE，即使之前并非如此，因此有效用户 ID 现在可能与事务之前不同。在函数 SET 子句中临时设置 session_authorization 也有类似的效果。一个相关的错误是，如果并行工作进程检查 current_setting('role')，它会看到 none，即使它应该看到其他值。

修复在附加或分离表分区时外键约束的目录状态更新（Jehan-Guillaume de Rorthais，Tender Wang，Álvaro Herrera）§ §

\n

如果被引用表是分区表，则独立的引用表与作为分区的引用表需要不同的目录条目。ATTACH/DETACH PARTITION 命令未能正确执行此转换。特别是在 DETACH 之后，现在独立的表将缺少外键强制触发器，这可能导致该表后来包含违反外键约束的行。随后的重新 ATTACH 也可能失败并产生令人意外的错误。

\n

修复方法是对现在独立的表的每个有问题的约束执行 ALTER TABLE DROP CONSTRAINT，然后重新添加该约束。如果重新添加约束失败，说明已经有错误数据混入。需要手动恢复引用表和被引用表之间的一致性，然后重新添加约束。

\n

以下查询可用于识别损坏的约束，并构造重建它们所需的命令：

\n
SELECT conrelid::pg_catalog.regclass AS \"constrained table\",\n       conname AS constraint,\n       confrelid::pg_catalog.regclass AS \"references\",\n       pg_catalog.format('ALTER TABLE %s DROP CONSTRAINT %I;',\n                         conrelid::pg_catalog.regclass, conname) AS \"drop\",\n       pg_catalog.format('ALTER TABLE %s ADD CONSTRAINT %I %s;',\n                         conrelid::pg_catalog.regclass, conname,\n                         pg_catalog.pg_get_constraintdef(oid)) AS \"add\"\nFROM pg_catalog.pg_constraint c\nWHERE contype = 'f' AND conparentid = 0 AND\n   (SELECT count(*) FROM pg_catalog.pg_constraint c2\n    WHERE c2.conparentid = c.oid) <>\n   ((SELECT count(*) FROM pg_catalog.pg_inherits i\n    WHERE (i.inhparent = c.conrelid OR i.inhparent = c.confrelid) AND\n      EXISTS (SELECT 1 FROM pg_catalog.pg_partitioned_table\n              WHERE partrelid = i.inhparent)) +\n    CASE WHEN pg_catalog.pg_partition_root(conrelid) = confrelid THEN\n              (SELECT count(*) FROM pg_catalog.pg_partition_tree(confrelid)\n                WHERE level = 1)\n         ELSE 0 END);\n

由于一个或多个 ADD CONSTRAINT 步骤可能会失败，应将查询输出保存到文件中，然后尝试执行每个步骤。

ATTACH/DETACH PARTITION commands failed to perform this conversion correctly. In particular, after DETACH the now stand-alone table would be missing foreign-key enforcement triggers, which could result in the table later containing rows that fail the foreign-key constraint. A subsequent re-ATTACH could fail with surprising errors, too. The way to fix this is to do ALTER TABLE DROP CONSTRAINT on the now stand-alone table for each faulty constraint, and then re-add the constraint. If re-adding the constraint fails, then some erroneous data has crept in. You will need to manually re-establish consistency between the referencing and referenced tables, then re-add the constraint.

此 tzdata 版本将旧的 System-V 兼容性区域名称更改为与对应地理区域重复；例如 PST8PDT 现在是 America/Los_Angeles 的别名。主要可见后果是，对于标准化时区引入之前的时间戳，该区域被认为代表命名位置的本地平均太阳时。例如，在 PST8PDT 中，timestamptz 输入如 1801-01-01 00:00 之前会被渲染为 1801-01-01 00:00:00-08，但现在会被渲染为 1801-01-01 00:00:00-07:52:58。

防止在 pg_dump 期间执行未经授权的代码（Masahiko Sawada）§

\n

能够创建和删除非临时对象的攻击者可以注入 SQL 代码，该代码将由并发的 pg_dump 会话以运行 pg_dump 的角色权限（通常是超级用户）来执行。该攻击涉及将序列或类似对象替换为会执行恶意代码的视图或外部表。为防止此问题，引入了新的服务器参数 restrict_nonsystem_relation_kind，可以禁止展开非内置视图以及访问外部表，并教会 pg_dump 在可用时设置该参数。请注意，只有当 pg_dump 和它正在导出的服务器都足够新以包含此修复时，才能防止该攻击。

将 pg_stats_ext 和 pg_stats_ext_exprs 条目的可见性限制为表所有者（Nathan Bossart）§

\n

这些视图未能隐藏涉及访问用户没有权限读取的列的表达式统计信息。视图列如 most_common_vals 可能暴露安全相关的数据。这里的潜在交互尚不完全清楚，因此为了安全起见，使这些视图中的行仅对关联表的所有者可见。

PostgreSQL 项目感谢 Lukas Fittl 报告此问题。（CVE-2024-4317）

\n

仅凭此修复本身只会修复新初始化的数据库集簇中的行为。如需在现有集簇中应用此更改，需要执行以下步骤：

\n
\n
    \n
  1. \n

    在 PostgreSQL 安装的 share 目录（通常位于类似 /usr/share/postgresql/ 的位置）中找到 SQL 脚本 fix-CVE-2024-4317.sql。确保使用适合你的 PostgreSQL 主版本的脚本。如果未看到此文件，则说明你的版本不受影响（只有 v14–v16 受影响），或者你的小版本太旧，尚未包含此修复。

    \n
    2. \n
  2. \n

    在集簇的每个数据库中，以超级用户身份运行 fix-CVE-2024-4317.sql 脚本。在 psql 中，命令如下：

    \n
    \\i /usr/share/postgresql/fix-CVE-2024-4317.sql\n
    \n

    （根据需要调整文件路径）。任何错误可能表明你使用了错误版本的脚本。多次运行该脚本不会有害。

    \n
    3. \n
  3. \n

    不要忘记包含 template0 和 template1 数据库，否则以后创建的数据库仍然存在该漏洞。要修复 template0，你需要临时允许它接受连接。执行：

    \n
    ALTER DATABASE template0 WITH ALLOW_CONNECTIONS true;\n
    \n

    然后在修复 template0 后，执行以下命令撤销：

    \n
    ALTER DATABASE template0 WITH ALLOW_CONNECTIONS false;\n

The potential interactions here are not fully clear, so in the interest of erring on the side of safety, make rows in these views visible only to the owner of the associated table. The PostgreSQL Project thanks Lukas Fittl for reporting this problem. (CVE-2024-4317) By itself, this fix will only fix the behavior in newly initdb'd database clusters. If you wish to apply this change in an existing cluster, you will need to do the following: Find the SQL script fix-CVE-2024-4317.sql in the share directory of the PostgreSQL installation (typically located someplace like /usr/share/postgresql/). Be sure to use the script appropriate to your PostgreSQL major version. If you do not see this file, either your version is not vulnerable (only v14–v16 are affected) or your minor version is too old to have the fix. In each database of the cluster, run the fix-CVE-2024-4317.sql script as superuser. In psql this would look like \\i /usr/share/postgresql/fix-CVE-2024-4317.sql (adjust the file path as appropriate). Any error probably indicates that you've used the wrong script version. It will not hurt to run the script more than once.

加强 REFRESH MATERIALIZED VIEW CONCURRENTLY 中的安全限制（Heikki Linnakangas）§ §

\n

并发刷新命令的一个步骤在弱安全限制下运行。如果物化视图的所有者能够说服超级用户或其他高权限用户对该视图执行并发刷新，则视图所有者可以控制以运行 REFRESH 的用户权限执行的代码。修复了这个问题，使所有用户确定的代码都以视图所有者身份运行，这是预期的行为。

此错误的唯一已知利用方式在 PostgreSQL 16.0 及更高版本中不起作用，因此 v16 在实际中可能不受影响。

修复 pg_dump，使得在枚举类型列上进行 hash 分区的分区表可以成功恢复（Tom Lane）§

\n

由于枚举值的 hash 码依赖于分配给枚举的 OID，在导出和恢复后它们通常是不同的，这意味着行往往需要进入与原来不同的分区。用户可以通过指定 --load-via-partition-root 选项来解决此问题；但由于不使用该选项几乎不可能成功，因此让 pg_dump 对此类表自动应用该选项。

同时，修复 pg_restore，使其在使用 --load-via-partition-root 模式时不再尝试在恢复前 TRUNCATE 目标表。这避免了死锁和数据丢失的风险。

The logic for dropping a table was broken and would miss removing all but the first such file, in two cases: drops of temporary tables and WAL replay of drops of regular tables. Applications that routinely create multi-gigabyte temporary tables could suffer significant disk space leakage.

避免在复制工作进程中函数语法错误后崩溃（Maxim Orlov，Anton Melnikov，Masahiko Sawada，Tom Lane）§

将时区数据文件更新为 tzdata 2022f 版本，包含智利、斐济、伊朗、约旦、墨西哥、巴勒斯坦和叙利亚的夏令时法规变更，以及智利、克里米亚、伊朗和墨西哥的历史修正。（Tom Lane）§

\n

此外，Europe/Kiev 时区已重命名为 Europe/Kyiv。另外，以下时区已合并到附近的、人口更多的、自 1970 年以来时钟一致的时区中：Antarctica/Vostok、Asia/Brunei、Asia/Kuala_Lumpur、Atlantic/Reykjavik、Europe/Amsterdam、Europe/Copenhagen、Europe/Luxembourg、Europe/Monaco、Europe/Oslo、Europe/Stockholm、Indian/Christmas、Indian/Cocos、Indian/Kerguelen、Indian/Mahe、Indian/Reunion、Pacific/Chuuk、Pacific/Funafuti、Pacific/Majuro、Pacific/Pohnpei、Pacific/Wake 和 Pacific/Wallis。（这间接影响了已经是这些时区别名的时区：Arctic/Longyearbyen、Atlantic/Jan_Mayen、Iceland、Pacific/Ponape、Pacific/Truk 和 Pacific/Yap。）America/Nipigon、America/Rainy_River、America/Thunder_Bay、Europe/Uzhgorod 和 Europe/Zaporozhye 也被合并到附近的时区中，因为发现它们声称的 1970 年后与这些时区的差异似乎是错误的。在所有这些情况下，之前的时区名称仍作为别名保留；但实际数据是所合并到的时区的数据。

\n

这些时区合并导致被合并时区的 1970 年前时区历史丢失，这对于期望 timestamptz 显示一致性的应用程序可能造成困扰。例如，存储的值 1944-06-01 12:00 UTC 在选择 Europe/Stockholm 时区时，之前会显示为 1944-06-01 13:00:00+01，但现在会显示为 1944-06-01 14:00:00+02。

(Tom Lane) Also, the Europe/Kiev zone has been renamed to Europe/Kyiv. Also, the following zones have been merged into nearby, more-populous zones whose clocks have agreed with them since 1970: Antarctica/Vostok, Asia/Brunei, Asia/Kuala_Lumpur, Atlantic/Reykjavik, Europe/Amsterdam, Europe/Copenhagen, Europe/Luxembourg, Europe/Monaco, Europe/Oslo, Europe/Stockholm, Indian/Christmas, Indian/Cocos, Indian/Kerguelen, Indian/Mahe, Indian/Reunion, Pacific/Chuuk, Pacific/Funafuti, Pacific/Majuro, Pacific/Pohnpei, Pacific/Wake and Pacific/Wallis. (This indirectly affects zones that were already links to one of these: Arctic/Longyearbyen, Atlantic/Jan_Mayen, Iceland, Pacific/Ponape, Pacific/Truk, and Pacific/Yap.) America/Nipigon, America/Rainy_River, America/Thunder_Bay, Europe/Uzhgorod, and Europe/Zaporozhye were also merged into nearby zones after discovering that their claimed post-1970 differences from those zones seem to have been errors. In all these cases, the previous zone name remains as an alias; but the actual data is that of the zone that was merged into. These zone mergers result in loss of pre-1970 timezone history for the merged zones, which may be troublesome for applications expecting consistency of timestamptz display. As an example, the stored value 1944-06-01 12:00 UTC would previously display as 1944-06-01 13:00:00+01 if the Europe/Stockholm zone is selected, but now it will read out as 1944-06-01 14:00:00+02. It is possible to build the time zone data files with options that will restore the older zone data, but that choice also inserts a lot of other old (and typically poorly-attested) zone data, resulting in more total changes from the previous release than accepting these upstream changes does. PostgreSQL has chosen to ship the tzdb data as-recommended, and so far as we are aware most major operating system distributions are doing likewise. However, if these changes cause significant problems for your application, a possible solution is to install a local build of the time zone data files using tzdb's backwards-compatibility options (see their PACKRATDATA and PACKRATLIST options).", "commit_aliases": ["97bb80b1b", "b1cb77bdf", "b3326a753", "c3d16eb3d", "e7c7605a7", "ebf48810b", "ec9a000d8"], "source_commits": ["c3d16eb3d"],

If you do not see this file, either your version is not vulnerable (only PostgreSQL 14, 15, and 16 are affected) or your minor version is too old to have the fix.\n\n\\i /usr/share/postgresql/fix-CVE-2024-4317.sql\n\nALTER DATABASE template0 WITH ALLOW_CONNECTIONS true;\n\nAfter executing the fix-CVE-2024-4317.sql script in template0 and template1 , you should revoke the ability for template0 to accept connections. You can do this with the following command:\n\nALTER DATABASE template0 WITH ALLOW_CONNECTIONS false;\n\nThe PostgreSQL project thanks Lukas Fittl for reporting this problem.", "affected_ranges": [{"from": "14", "until": "14.12"}, {"from": "15", "until": "15.7"}, {"from": "16", "until": "16.3"}], "first_published": "2024-05-09", "fixed_version": "15.7", "severity": "低危", "status_label": "目标版本已修复"}, {"id": "CVE-2024-10977", "url": "https://www.postgresql.org/support/security/CVE-2024-10977/", "fixed": {"12": "12.21", "13": "13.17", "14": "14.14", "15": "15.9", "16": "16.5", "17": "17.1"}, "score": 3.1, "title": "使 libpq 丢弃在 SSL 或 GSS 协议协商期间收到的错误消息", "vector": "AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N", "cna_url": "https://cveawg.mitre.org/api/cve/CVE-2024-10977", "affected": {"12": "12", "13": "13", "14": "14", "15": "15", "16": "16", "17": "17"}, "component": "client", "published": {"12": "2024-11-14", "13": "2024-11-14", "14": "2024-11-14", "15": "2024-11-14", "16": "2024-11-14", "17": "2024-11-14"}, "introduced": {}, "cvss_version": "3.0", "description_en": "Client use of server error message in PostgreSQL allows a server not trusted under current SSL or GSS settings to furnish arbitrary non-NUL bytes to the libpq application.
