TITLE:
Roxio Toast Titanium Insecure Temporary File Creation

SECUNIA ADVISORY ID:
SA21867

VERIFY ADVISORY:
http://secunia.com/advisories/21867/

CRITICAL:
Not critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
Roxio Toast Titanium 7.x
http://secunia.com/product/11582/

DESCRIPTION:
Netragard has reported a vulnerability in Roxio Toast Titanium, which
can be exploited by malicious, local users to gain escalated
privileges.

The vulnerability is caused due to the "dejavu_manual.rb" Ruby script
being created insecurely in the "/tmp" directory. This can be
exploited via a race condition to execute arbitrary code with root
privileges when an administrator does a manual backup in Deja Vu.

Some other Ruby scripts may also be created insecurely.

The vulnerability has been reported in version 7. Other versions may
also be affected.

SOLUTION:
Grant only trusted users access to affected systems.

PROVIDED AND/OR DISCOVERED BY:
Adriel T. Desautels, Netragard
