DESCRIPTION:
A security issue has been reported in the PAR 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 temporary
files in an insecure manner, which can be exploited to e.g. overwrite
arbitrary files via symlink attacks.

The security issue is reported in versions prior to 1.003.

SOLUTION:
Update to version 1.003.

PROVIDED AND/OR DISCOVERED BY:
Reported by John Lightsey in a bug report.
