DESCRIPTION:
Ubuntu has issued an update for open-iscsi. This fixes a security
issue, which can be exploited by malicious, local users to perform
certain actions with escalated privileges.

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

SOLUTION:
Apply updated packages.
