ID:	201508-03

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	Architecture(s)
net-misc/icecast	< 2.4.2	>= 2.4.2	All supported architectures

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"
