http://secunia.com/advisories/16833/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
GNOME Workstation Command Center (GWCC) 0.x
http://secunia.com/product/5662/

DESCRIPTION:
D1g1t4lLeech has reported a vulnerability in GWCC, which can be
exploited by malicious, local users to perform certain actions on a
vulnerable system with escalated privileges.

The vulnerability is caused due to the temporary file "gwcc_out.txt"
being created insecurely in "/tmp" by "perform_file_save()" when
printing. This can be exploited via symlink attacks to create or
overwrite arbitrary files with the privileges of the user running the
affected application.

The vulnerability has been reported in version 0.9.8. Other versions
may also be affected.

SOLUTION:
Grant only trusted users access to affected systems.

PROVIDED AND/OR DISCOVERED BY:
