SOFTWARE:
Xsan Filesystem 1.x
http://secunia.com/product/11577/

DESCRIPTION:
A vulnerability has been reported in Xsan Filesystem, which
potentially can be exploited by malicious, local users to gain
escalated privileges.

The vulnerability is caused due to a boundary error in the Xsan
Filesystem driver when processing path names and can be exploited to
cause a buffer overflow.

Successful exploitation may cause a vulnerable system to crash or
allow execution of arbitrary code with system privileges, but
requires write access to an Xsan volume.
