CVE-2008-4576
HighSummary
Podatność w protokole SCTP w jądrze Linuksa przed wersją 2.6.25.18 pozwala zdalnym atakującym na wywołanie odmowy usługi (OOPS) poprzez wysłanie INIT-ACK, który informuje, że partner nie obsługuje autoryzacji. To powoduje, że funkcja sctp_process_init sprząta aktywne transporty i wywołuje OOPS po wygaśnięciu timera T1-Init.
Risk Assessment
Atakujący mogą wykorzystać tę podatność do zakłócenia działania systemu, co prowadzi do odmowy usługi. Może to wpłynąć na dostępność usług korzystających z protokołu SCTP w organizacji.
Recommendation
Zaleca się aktualizację jądra Linuksa do wersji 2.6.25.18 lub nowszej, aby usunąć tę podatność. Dodatkowo, monitorowanie i zabezpieczenie systemów przed nieautoryzowanym dostępem może pomóc w minimalizacji ryzyka.

Original NVD description (English source)
sctp in Linux kernel before 2.6.25.18 allows remote attackers to cause a denial of service (OOPS) via an INIT-ACK that states the peer does not support AUTH, which causes the sctp_process_init function to clean up active transports and triggers the OOPS when the T1-Init timer expires.
