## Description

Integer overflow in the sctp\_setsockopt\_auth\_key function in
net/sctp/socket.c in the Stream Control Transmission Protocol (sctp)
implementation in the Linux kernel 2.6.24-rc1 through 2.6.26.3 allows
remote attackers to cause a denial of service (panic) or possibly have
unspecified other impact via a crafted sca\_keylength field associated with
the SCTP\_AUTH\_KEY option.

### From the Ubuntu Security Team

It was discovered that the Stream Control Transmission Protocol (SCTP)
did not correctly validate the key length in the SCTP\_AUTH\_KEY option.
If SCTP is in use, a remote attacker could send specially crafted network
traffic that would crash the system, leading to a denial of service.
