CVE-2013-3183
HighSummary
Implementacja TCP/IP w systemach Microsoft Windows Vista SP2, Windows Server 2008 SP2 i R2 SP1, Windows 7 SP1, Windows 8, Windows Server 2012 oraz Windows RT nieprawidłowo przydziela pamięć dla przychodzących pakietów ICMPv6, co pozwala zdalnym atakującym na spowodowanie odmowy usługi (zawieszenie systemu) poprzez odpowiednio skonstruowane pakiety.
Risk Assessment
Atakujący mogą wykorzystać tę podatność do zdalnego zawieszenia systemu, co prowadzi do przerwy w dostępności usług i potencjalnych strat finansowych dla organizacji.
Recommendation
Zaleca się aktualizację systemów do najnowszych wersji, które zawierają poprawki zabezpieczeń eliminujące tę podatność oraz monitorowanie ruchu sieciowego w celu wykrywania podejrzanych pakietów ICMPv6.

Original NVD description (English source)
The TCP/IP implementation in Microsoft Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows Server 2012, and Windows RT does not properly perform memory allocation for inbound ICMPv6 packets, which allows remote attackers to cause a denial of service (system hang) via crafted packets, aka "ICMPv6 Vulnerability."
