> CVE-2024-7348
> PostgreSQL relation replacement during pg_dump executes arbitrary SQL
>
> 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.
>
> The PostgreSQL project thanks Noah Misch for reporting this problem.
