An attack requires EXECUTE permission on the function, which must itself contain a function call having inexact argument type match. For example, length('foo'::varchar) and length('foo') are inexact, while length('foo'::text) is exact.\n\nAs part of exploiting this vulnerability, the attacker uses CREATE DOMAIN to create a type in a pg_temp schema. The attack pattern and fix are similar to that for CVE-2007-2138 .\n\nWriting SECURITY DEFINER functions continues to require following the considerations noted in the documentation:\n\nhttps://www.postgresql.org/docs/current/sql-createfunction.html#SQL-CREATEFUNCTION-SECURITY\n\nThe PostgreSQL project thanks Tom Lane for reporting this problem.", "description_language": "en", "fixed": "11.5", "fixed_url": "/docs/compare/?release=11.5", "affected": "11", "component": "core server", "mentions": [{"build": "11.5", "version": "11.5", "title": "\u4f7f\u7528\u51fd\u6570\u5f0f\u7c7b\u578b\u8f6c\u6362\u8bed\u6cd5\u8f6c\u6362\u4e3a\u4e34\u65f6\u7c7b\u578b\u65f6\uff0c\u8981\u6c42\u4f7f\u7528\u6a21\u5f0f\u9650\u5b9a", "url": "/docs/compare/?release=11.5#11.5-8f9963118448ea50"}], "evidence": "branch-matrix"}, {"id": "CVE-2019-10164", "title": "Stack-based buffer overflow via setting a password", "url": "https://www.postgresql.org/support/security/CVE-2019-10164/", "score": 7.5, "vector": "AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H", "description": "An authenticated user could create a stack-based buffer overflow by changing their own password to a purpose-crafted value.
