Package name shorewall
Date July 20th, 2005
Advisory ID MDKSA-2005:123
Affected versions 10.0, 10.1, CS3.0, MNF2.0, 10.2
Synopsis Updated shorewall packages fix vulnerability

Problem Description

A vulnerability was discovered in all versions of shorewall where a
client accepted by MAC address filtering is able to bypass any other
rule. If MACLIST_TTL is set to a value greater than 0 or
MACLIST_DISPOSITION is set to ACCEPT in shorewall.conf, and a client
is positively identified through its MAC address, it bypasses all other
policies and rules in place, gaining access to all open services on the
firewall.

Shorewall 2.0.17 is provided which fixes this issue.
