ON CONFLICT ... DO UPDATE command on a purpose-crafted table, an authenticated database user could read arbitrary bytes of server memory. The highest threat from this vulnerability is to data confidentiality. Scope: local bullseye: resolved (fixed in 13.3-1)

CVE-2021-3677 [MEDIUM] CVE-2021-3677: postgresql-13 - A flaw was found in postgresql. A purpose-crafted query can read arbitrary bytes... A flaw was found in postgresql. A purpose-crafted query can read arbitrary bytes of server memory. In the default configuration, any authenticated database user can complete this attack at will. The attack does not require the ability to create objects. If server settings include max_worker_processes=0, the known versions of this attack are infeasible. However

CVE-2025-12818 [MEDIUM] CVE-2025-12818: postgresql-13 - Integer wraparound in multiple PostgreSQL libpq client library functions allows ... Integer wraparound in multiple PostgreSQL libpq client library functions allows an application input provider or network peer to cause libpq to undersize an allocation and write out-of-bounds by hundreds of megabytes. This results in a segmentation fault for the application using libpq. Versions before PostgreSQL 18.1, 17.7, 16.11, 15.15, 14.20, and 13.23 ar

CVE-2024-10976 [HIGH] CVE-2024-10976: postgresql-13 - Incomplete tracking in PostgreSQL of tables with row security allows a reused qu... Incomplete tracking in PostgreSQL of tables with row security allows a reused query to view or change different rows from those intended. CVE-2023-2455 and CVE-2016-2193 fixed most interaction between row security and user ID changes. They missed cases where a subquery, WITH query, security invoker view, or SQL-language function references a table with a row-l

CVE-2025-4207 [MEDIUM] CVE-2025-4207: postgresql-13 - Buffer over-read in PostgreSQL GB18030 encoding validation allows a database inp... Buffer over-read in PostgreSQL GB18030 encoding validation allows a database input provider to achieve temporary denial of service on platforms where a 1-byte over-read can elicit process termination. This affects the database server and also libpq. Versions before PostgreSQL 17.5, 16.9, 15.13, 14.18, and 13.21 are affected. Scope: local bullseye: resolved (fi

CVE-2021-23222 [MEDIUM] CVE-2021-23222: postgresql-13 - A man-in-the-middle attacker can inject false responses to the client's first fe... A man-in-the-middle attacker can inject false responses to the client's first few queries, despite the use of SSL certificate verification and encryption. Scope: local bullseye: resolved (fixed in 13.5-0+deb11u1)

CVE-2023-2455 [MEDIUM] CVE-2023-2455: postgresql-13 - Row security policies disregard user ID changes after inlining; PostgreSQL could... Row security policies disregard user ID changes after inlining; PostgreSQL could permit incorrect policies to be applied in certain cases where role-specific policies are used and a given query is planned under one role and then executed under other roles. This scenario can happen under security definer functions or when a common user and query is planned init

CVE-2023-5868 [MEDIUM] CVE-2023-5868: postgresql-13 - A memory disclosure vulnerability was found in PostgreSQL that allows remote use... A memory disclosure vulnerability was found in PostgreSQL that allows remote users to access sensitive information by exploiting certain aggregate function calls with 'unknown'-type arguments. Handling 'unknown'-type values from string literals without type designation can disclose bytes, potentially revealing notable and confidential information. This issue e

CVE-2026-2003 [MEDIUM] CVE-2026-2003: postgresql-13 - Improper validation of type "oidvector" in PostgreSQL allows a database user to ... Improper validation of type "oidvector" in PostgreSQL allows a database user to disclose a few bytes of server memory. We have not ruled out viability of attacks that arrange for presence of confidential information in disclosed bytes, but they seem unlikely. Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21 are affected. Scope: local bullseye: re

CVE-2024-4317 [LOW] CVE-2024-4317: postgresql-13 - Missing authorization in PostgreSQL built-in views pg_stats_ext and pg_stats_ext... Missing authorization in PostgreSQL built-in views pg_stats_ext and pg_stats_ext_exprs allows an unprivileged database user to read most common values and other statistics from CREATE STATISTICS commands of other users. The most common values may reveal column values the eavesdropper could not otherwise read or results of functions they cannot execute. Installing

CVE-2021-20229 [MEDIUM] CVE-2021-20229: postgresql-13 - A flaw was found in PostgreSQL in versions before 13.2. This flaw allows a user ... A flaw was found in PostgreSQL in versions before 13.2. This flaw allows a user with SELECT privilege on one column to craft a special query that returns all columns of the table. The highest threat from this vulnerability is to confidentiality. Scope: local bullseye: resolved (fixed in 13.2-1)

CVE-2024-10978 [MEDIUM] CVE-2024-10978: postgresql-13 - Incorrect privilege assignment in PostgreSQL allows a less-privileged applicatio... Incorrect privilege assignment in PostgreSQL allows a less-privileged application user to view or change different rows from those intended. An attack requires the application to use SET ROLE, SET SESSION AUTHORIZATION, or an equivalent feature. The problem arises when an application query uses parameters from the attacker or conveys query results to the att

CVE-2021-3393 [MEDIUM] CVE-2021-3393: postgresql-13 - An information leak was discovered in postgresql in versions before 13.2, before... An information leak was discovered in postgresql in versions before 13.2, before 12.6 and before 11.11. A user having UPDATE permission but not SELECT permission to a particular column could craft queries which, under some circumstances, might disclose values from that column in error messages. An attacker could use this flaw to obtain information stored in a

CVE-2023-39418 [LOW] CVE-2023-39418: postgresql-13 - A vulnerability was found in PostgreSQL with the use of the MERGE command, which... A vulnerability was found in PostgreSQL with the use of the MERGE command, which fails to test new rows against row security policies defined for UPDATE and SELECT. If UPDATE and SELECT policies forbid some rows that INSERT policies do not forbid, a user could store such rows. Scope: local bullseye: resolved

CVE-2023-5870 [LOW] CVE-2023-5870: postgresql-13 - A flaw was found in PostgreSQL involving the pg_cancel_backend role that signals... A flaw was found in PostgreSQL involving the pg_cancel_backend role that signals background workers, including the logical replication launcher, autovacuum workers, and the autovacuum launcher. Successful exploitation requires a non-core extension with a less-resilient background worker and would affect that specific background worker only. This issue may allow a

CVE-2024-10977 [LOW] CVE-2024-10977: postgresql-13 - Client use of server error message in PostgreSQL allows a server not trusted und... 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. For example, a man-in-the-middle attacker could send a long error message that a human or screen-scraper user of psql mistakes for valid query results. This is probably not a concern for clie

CVE-2022-41862 [LOW] CVE-2022-41862: postgresql-13 - In PostgreSQL, a modified, unauthenticated server can send an unterminated strin... In PostgreSQL, a modified, unauthenticated server can send an unterminated string during the establishment of Kerberos transport encryption. In certain conditions a server can cause a libpq client to over-read and report an error message containing uninitialized bytes. Scope: local bullseye: resolved (fixed in 13.10-0+deb11u1)

CVE-2025-8713 [HIGH] CVE-2025-8713: postgresql-13 - PostgreSQL optimizer statistics allow a user to read sampled data within a view ... PostgreSQL optimizer statistics allow a user to read sampled data within a view that the user cannot access. Separately, statistics allow a user to read sampled data that a row security policy intended to hide. PostgreSQL maintains statistics for tables by sampling data available in columns; this data is consulted during the query planning process. Prior to this

CVE-2025-12817 [LOW] CVE-2025-12817: postgresql-13 - Missing authorization in PostgreSQL CREATE STATISTICS command allows a table own... Missing authorization in PostgreSQL CREATE STATISTICS command allows a table owner to achieve denial of service against other CREATE STATISTICS users by creating in any schema. A later CREATE STATISTICS for the same name, from a user having the CREATE privilege, would then fail. Versions before PostgreSQL 18.1, 17.7, 16.11, 15.15, 14.20, and 13.23 are affected.
