Synopsis
========
GNU Gadu, CenterICQ, Kadu, EKG and libgadu are vulnerable to an integer
overflow which could potentially lead to the execution of arbitrary
code or a Denial of Service.
Background
==========
GNU Gadu, CenterICQ, Kadu and EKG are instant messaging applications
created to support Gadu Gadu instant messaging protocol. libgadu is a
library that implements the client side of the Gadu-Gadu protocol.

Description
===========
GNU Gadu, CenterICQ, Kadu, EKG and libgadu are vulnerable to an integer
overflow.
Impact
======
A remote attacker could exploit the integer overflow to execute
arbitrary code or cause a Denial of Service.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All GNU Gadu users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-im/gnugadu-2.2.6-r1"
All Kadu users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-im/kadu-0.4.1"
All EKG users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-im/ekg-1.6_rc3"
All libgadu users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-libs/libgadu-20050719"
All CenterICQ users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-im/centericq-4.20.0-r3"
CenterICQ is no longer distributed with Gadu Gadu support, affected
users are encouraged to migrate to an alternative package.
