Amazon Linux 2 Security Advisory: ALASPOSTGRESQL12-2024-012
Advisory Release Date: 2024-09-26 01:10 Pacific
Advisory Updated Date: 2024-10-02 14:50 Pacific
Time-of-check Time-of-use (TOCTOU) race condition in pg_dump in PostgreSQL allows an object creator to execute arbitrary SQL functions as the user running pg_dump, which is often a superuser. The attack involves replacing another relation type with a view or foreign table. The attack requires waiting for pg_dump to start, but winning the race condition is trivial if the attacker retains an open transaction. Versions before PostgreSQL 16.4, 15.8, 14.13, 13.16, and 12.20 are affected. (CVE-2024-7348)
Affected Packages:
