Security Advisory - 2008-11-22
------------------------------------------------------------------------------
Summary:
Important: No-IP Linux DUC (Dynamic Update Client)

An updated version of the No-IP Linux Dynamic Update Client that fixes
a security issue is now available.

This update has been rated as having important security impact.

Description:
Versions 2.1.1- > 2.1.8 are prone to a stack-based buffer-overflow due to
a boundary error when processing HTTP responses received from the update
server. This can be exploited and cause a stack-based buffer overflow when
performing an update.

A malicious user could exploit this by faking the No-IP update server
via DNS poisoning or a man in the middle attack. This can cause a denial of
service (client crash) or
potentially execute arbitrary code on the computer the client is running on.

Users running versions 2.1.8 and older are encouraged to upgrade to the most
recent version, 2.1.9
