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 remote high privileged user to launch a denial of service (DoS) attack.

Ubuntu Security Notice 6296-1 - It was discovered that PostgreSQL incorrectly handled certain extension script substitutions. An attacker having database-level CREATE privileges can use this issue to execute arbitrary code as the bootstrap superuser. It was discovered that PostgreSQL incorrectly handled the MERGE command.

Ubuntu Security Notice 6296-1 - It was discovered that PostgreSQL incorrectly handled certain extension script substitutions.

A remote attacker could possibly use this issue to bypass certain UPDATE and SELECT policies. This issue only affected Ubuntu 23.04.
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.
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 bootstrap superuser.
