▸ GLSA 201508-02 libgadu: Multiple vulnerabilities this version unaffected normal remote 2015-08-15

Multiple vulnerabilities have been found in libgadu, the worst of which may result in execution of arbitrary code.

Announced: 2015-08-15
Revised: 2015-08-15
Access: remote
Bugs: #490238 #505558 #510714
Advisory: https://security.gentoo.org/glsa/201508-02

Affected packages

Package	Arch	Vulnerable	Unaffected
net-libs/libgadu	*	< 1.12.0	>= 1.12.0

Background

libgadu is a library that implements the client side of the Gadu-Gadu protocol.

Description

libgadu contains multiple vulnerabilities:

X.509 certificates are not properly validated (CVE-2013-4488)
A integer overflow error could lead to a buffer overflow (CVE-2013-6487)
Malformed responses from a Gadu-Gadu file relay server are not properly handled (CVE-2014-3775)

Impact

A remote attacker may be able to execute arbitrary code with the privileges of the process, cause a Denial of Service condition, or spoof servers.

Workaround

There is no known workaround at this time.

Resolution

All libgadu users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-libs/libgadu-1.12.0"

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.
