USN-4027-1

Alexander Lakhin discovered that PostgreSQL incorrectly handled authentication. An authenticated attacker or a rogue server could use this issue to cause PostgreSQL to crash, resulting in a denial of service, or possibly execute arbitrary code. The default compiler options for affected releases should reduce the vulnerability to a denial of service.
