CVE-2023-5869 [HIGH] CVE-2023-5869: postgresql-13 - A flaw was found in PostgreSQL that allows authenticated database users to execu... A flaw was found in PostgreSQL that allows authenticated database users to execute arbitrary code through missing overflow checks during SQL array value modification. This issue exists due to an integer overflow during array modification where a remote user can trigger the overflow by providing specially crafted data. This enables the execution of arbitrary code

CVE-2023-39417 [HIGH] CVE-2023-39417: postgresql-13 - IN THE EXTENSION SCRIPT, a SQL Injection vulnerability was found in PostgreSQL i... IN THE EXTENSION SCRIPT, a SQL Injection vulnerability was found in PostgreSQL if it uses @extowner@, @extschema@, or @extschema:...@ inside a quoting construct (dollar quoting, '', or ""). If an administrator has installed files of a vulnerable, trusted, non-bundled extension, an attacker with database-level CREATE privilege can execute arbitrary code as the

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

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-2022-2625 [HIGH] CVE-2022-2625: postgresql-13 - A vulnerability was found in PostgreSQL. This attack requires permission to crea... A vulnerability was found in PostgreSQL. This attack requires permission to create non-temporary objects in at least one schema, the ability to lure or wait for an administrator to create or update an affected extension in that schema, and the ability to lure or wait for a victim to use the object targeted in CREATE OR REPLACE or CREATE IF NOT EXISTS. Given all

CVE-2022-1552 [HIGH] CVE-2022-1552: postgresql-13 - A flaw was found in PostgreSQL. There is an issue with incomplete efforts to ope... A flaw was found in PostgreSQL. There is an issue with incomplete efforts to operate safely when a privileged user is maintaining another user's objects. The Autovacuum, REINDEX, CREATE INDEX, REFRESH MATERIALIZED VIEW, CLUSTER, and pg_amcheck commands activated relevant protections too late or not at all during the process. This flaw allows an attacker with per

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-2021-32027 [HIGH] CVE-2021-32027: postgresql-13 - A flaw was found in postgresql in versions before 13.3, before 12.7, before 11.1... A flaw was found in postgresql in versions before 13.3, before 12.7, before 11.12, before 10.17 and before 9.6.22. While modifying certain SQL array values, missing bounds checks let authenticated database users write arbitrary bytes to a wide area of server memory. The highest threat from this vulnerability is to data confidentiality and integrity as well as

CVE-2021-23214 [HIGH] CVE-2021-23214: postgresql-13 - When the server is configured to use trust authentication with a clientcert requ... When the server is configured to use trust authentication with a clientcert requirement or to use cert authentication, a man-in-the-middle attacker can inject arbitrary SQL queries when a connection is first established, despite the use of SSL certificate verification and encryption. Scope: local bullseye: resolved (fixed in 13.5-0+deb11u1)

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)

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

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-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
