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"
