Null pointer dereference

The Stream Control Transmission Protocol SCTP module in FreeBSD 9.3 before p33, 10.1 before p26, and 10.2 before p9, when the kernel is configured for IPv6, allows remote attackers to cause a denial of service assertion failure or NULL pointer dereference and kernel panic via a crafted ICMPv6...

FreeBSD -- SCTP ICMPv6 error message vulnerability

Problem Description: A lack of proper input checks in the ICMPv6 processing in the SCTP stack can lead to either a failed kernel assertion or to a NULL pointer dereference. In either case, a kernel panic will follow. Impact: A remote, unauthenticated attacker can reliably trigger a kernel panic i...
