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.
