Linux Kernel "CIFSTCon()" Buffer Overflow Vulnerability

SECUNIA ADVISORY ID:
SA34644

VERIFY ADVISORY:
http://secunia.com/advisories/34644/

DESCRIPTION:
A vulnerability has been reported in the Linux Kernel, which can be
exploited by malicious people to potentially compromise a vulnerable
system.

The vulnerability is caused due to a boundary error within the
"CIFSTCon()" function in fs/cifs/connect.c. This can be exploited to
cause a buffer overflow by e.g. sending a specially crafted Tree
Connect response to a vulnerable client.

SOLUTION:
Do not mount from untrusted CIFS servers.
