CVE-2011-2482
HighSummary
Poprawka Red Hat dotycząca funkcji sctp_sock_migrate w jądrze Linux przed wersją 2.6.21, używana w Red Hat Enterprise Linux (RHEL) 5, umożliwia zdalnym atakującym spowodowanie odmowy usługi (dereferencja wskaźnika NULL i OOPS) za pomocą spreparowanego pakietu SCTP.
Risk Assessment
Atakujący może wykorzystać tę podatność do zdalnego wywołania błędu, co prowadzi do niedostępności usługi. Może to wpłynąć na stabilność i dostępność systemów korzystających z podatnej wersji jądra.
Recommendation
Zaleca się aktualizację jądra Linux do wersji 2.6.21 lub nowszej, aby usunąć tę podatność. Należy również monitorować ruch SCTP w celu wykrycia potencjalnych prób ataku.

Original NVD description (English source)
A certain Red Hat patch to the sctp_sock_migrate function in net/sctp/socket.c in the Linux kernel before 2.6.21, as used in Red Hat Enterprise Linux (RHEL) 5, allows remote attackers to cause a denial of service (NULL pointer dereference and OOPS) via a crafted SCTP packet.
