CVE-2026-6479
MediumSummary
Nieograniczona rekurencja w negocjacji SSL i GSS w PostgreSQL pozwala atakującemu, który ma dostęp do gniazda AF_UNIX PostgreSQL, na osiągnięcie trwałego odmowy usługi. Jeśli SSL i GSS są wyłączone, atakujący może to samo zrobić, uzyskując dostęp do gniazda TCP PostgreSQL. Dotyczy wersji przed PostgreSQL 18.
Risk Assessment
Organizacja narażona jest na ataki typu denial of service, co może prowadzić do przestojów w działaniu systemu baz danych. Umożliwienie atakującemu dostępu do gniazd może skutkować poważnymi konsekwencjami dla dostępności usług.
Recommendation
Zaleca się aktualizację PostgreSQL do wersji 18 lub nowszej, aby zniwelować ryzyko związane z tą podatnością. Dodatkowo, należy ograniczyć dostęp do gniazd PostgreSQL tylko do zaufanych użytkowników.

Original NVD description (English source)
Uncontrolled recursion in PostgreSQL SSL and GSS negotiation allows an attacker able to connect to a PostgreSQL AF_UNIX socket to achieve sustained denial of service. If SSL and GSS are both disabled, an attacker can do the same via access to a PostgreSQL TCP socket. Versions before PostgreSQL 18.
