Title:	GNU Gadu, CenterICQ, Kadu, EKG, libgadu: Remote code execution in Gadu library
Date:	07/27/2005
Bugs:	#99816, #99890, #99583
ID:	200507-26

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.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-im/gnugadu	< 2.2.6-r1	>= 2.2.6-r1	All supported architectures
net-im/centericq	< 4.20.0-r3	>= 4.20.0-r3	All supported architectures
net-im/kadu	< 0.4.1	>= 0.4.1	All supported architectures
net-im/ekg	< 1.6_rc3	>= 1.6_rc3	All supported architectures
net-libs/libgadu	< 1.7.0_pre20050719	>= 1.7.0_pre20050719	All supported architectures

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.
