DESCRIPTION:
A security issue has been discovered in virtualenv, which can be
exploited by malicious, local users to perform certain actions with
escalated privileges.

The security issue is caused due to the virtualenv.py script creating
temporary files in an insecure manner, which can be exploited to e.g.
overwrite arbitrary files via symlink attacks.

The security issue is confirmed in version 1.4.9. Prior versions may
also be affected.

SOLUTION:
Update to version 1.5.

PROVIDED AND/OR DISCOVERED BY:
