Synopsis
========

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

Background
==========

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

Affected packages
=================

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

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.

All libgadu users should upgrade to the latest version:

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

Synopsis
========

A bug in the Icecast code handling source client URL authentication
causes a Denial of Service condition.

Background
==========

Icecast is an open source alternative to shoutcast that supports mp3,
ogg (vorbis/theora) and aac streaming.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-misc/icecast < 2.4.2 >= 2.4.2

Description
===========

When stream_auth handler is defined for URL authentication and a
request is sent without login credentials, a Denial of Service
condition can occur.

Impact
======

A remote attacker could possibly cause a Denial of Service condition.

Workaround
==========

Users of affected versions can change stream_auth mountpoints to use
password authentication instead.

Resolution
==========

All icecast users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/icecast-2.4.2"
