CRITICAL:
Not critical
IMPACT:
Privilege escalation

Local system
SOFTWARE:
vobcopy 1.x
http://secunia.com/product/16364/
DESCRIPTION:
Joey Hess has reported a security issue in vobcopy, which can be
exploited by malicious, local users to perform certain actions with
escalated privileges.
The security issue is caused due to vobcopy appending to
"/tmp/vobcopy.bla" when running in quiet mode. This can be exploited
via symlink attacks to append certain data to arbitrary files.
SOLUTION:
Do not run vobcopy in quiet mode. Restrict access to trusted people
only.
