CVE-2010-2495
HighSummary
Funkcja pppol2tp_xmit w sterownikach L2TP w jądrze Linux przed wersją 2.6.34 nieprawidłowo waliduje pewne wartości związane z interfejsem. To może umożliwić atakującym spowodowanie odmowy usługi (dereferencja wskaźnika NULL i OOPS) lub potencjalnie inne nieokreślone skutki związane ze zmianą routingu.
Risk Assessment
Organizacje mogą być narażone na ataki, które prowadzą do odmowy usługi, co może wpłynąć na dostępność systemów. Dodatkowo, nieokreślone skutki mogą prowadzić do dalszych problemów z bezpieczeństwem.
Recommendation
Zaleca się aktualizację jądra Linux do wersji 2.6.34 lub nowszej, aby usunąć tę podatność. Należy również monitorować systemy pod kątem nieautoryzowanych zmian w routingu.

Original NVD description (English source)
The pppol2tp_xmit function in drivers/net/pppol2tp.c in the L2TP implementation in the Linux kernel before 2.6.34 does not properly validate certain values associated with an interface, which allows attackers to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact via vectors related to a routing change.
