[GLSA-200503-27] Xzabite dyndnsupdate: Multiple vulnerabilities

Vulnerability Assessment Summary
Xzabite dyndnsupdate: Multiple vulnerabilities

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200503-27
(Xzabite dyndnsupdate: Multiple vulnerabilities)

Toby Dickenson discovered that dyndnsupdate suffers from multiple
overflows.

Impact

A remote attacker, posing as a dyndns.org server, could execute
arbitrary code with the rights of the user running dyndnsupdate.

Workaround

There is no known workaround at this time.

Solution:
Currently, there is no released version of dyndnsupdate that
contains a fix for these issues. The original xzabite.org distribution
site is dead, the code contains several other problems and more secure
alternatives exist, such as the net-dns/ddclient package. Therefore,
the dyndnsupdate package has been hard-masked prior to complete removal
from Portage, and current users are advised to unmerge the package:
# emerge --unmerge net-misc/dyndnsupdate

Network Security Threat Level: Medium
