DESCRIPTION:
A security issue has been discovered in the Proc::ProcessTable module
for Perl, which can be exploited by malicious, local users to perform
certain actions with escalated privileges.

The security issue is caused due to the application using a temporary
file in an insecure manner, which can be exploited to e.g. overwrite
arbitrary files via symlink attacks.

The security issue is confirmed in version 0.45. Other versions may
also be affected.

SOLUTION:
Restrict access to trusted users only.

PROVIDED AND/OR DISCOVERED BY:
Reported by Ansgar Burchardt in a Debian bug report.
