Synopsis
========
PeerCast suffers from a format string vulnerability that could allow
arbitrary code execution.
Background
==========
PeerCast is a media streaming system based on P2P technology.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-sound/peercast < 0.1212 >= 0.1212
Description
===========
James Bercegay of the GulfTech Security Research Team discovered that
PeerCast insecurely implements formatted printing when receiving a
request with a malformed URL.
Impact
======
A remote attacker could exploit this vulnerability by sending a request
with a specially crafted URL to a PeerCast server to execute arbitrary
code.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All PeerCast users should upgrade to the latest available version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-sound/peercast-0.1212"
