DESCRIPTION:
Some security issues have been reported in mrouted, which can be
exploited by malicious, local users to perform certain actions with
escalated privileges.

The security issues are caused due to mrouted creating temporary
files in an insecure manner, which can be exploited to e.g. overwrite
arbitrary files via symlink attacks.

The security issues are reported in versions prior to 3.9.5.

SOLUTION:
Update to version 3.9.5.

PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
