DESCRIPTION:
SUSE has acknowledged a security issue in kbd, which can be exploited
by malicious, local users to perform certain actions with escalated
privileges.

The security issue is caused due to the /etc/init.d/kbd script
creating the /dev/shm/defkeymap.map file in an insecure manner, which
can be exploited to e.g. overwrite arbitrary files via symlink
attacks.

SOLUTION:
Apply updated packages via the zypper package manager.
