Denial of Service Vulnerability in Linux Kernel SCTP Implementation

CVE-2013-2206 · MEDIUM Severity

AV:N/AC:H/AU:N/C:N/I:N/A:C

The sctp_sf_do_5_2_4_dupcook function in net/sctp/sm_statefuns.c in the SCTP implementation in the Linux kernel before 3.8.5 does not properly handle associations during the processing of a duplicate COOKIE ECHO chunk, which allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via crafted SCTP traffic.
