CVE-2008-3584
HighSummary
NetBSD w wersjach 3.0, 3.1 i 4.0 nieprawidłowo sprawdza długość tagu pakietu PPPoE, co może prowadzić do awarii systemu. Zdalni atakujący mogą wykorzystać tę lukę, wysyłając specjalnie przygotowany pakiet PPPoE.
Risk Assessment
Luka ta może prowadzić do odmowy usługi, co wpływa na dostępność systemu i może zakłócić działanie usług w organizacji.
Recommendation
Zaleca się aktualizację systemu NetBSD do najnowszej wersji, aby usunąć tę podatność oraz monitorowanie ruchu PPPoE w celu wykrycia potencjalnych ataków.

Original NVD description (English source)
NetBSD 3.0, 3.1, and 4.0, when a pppoe instance exists, does not properly check the length of a PPPoE packet tag, which allows remote attackers to cause a denial of service (system crash) via a crafted PPPoE packet.
