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"
