Synopsis
========
Asterisk contains a bug in the IAX2 channel driver making it vulnerable
to the remote execution of arbitrary code.
Background
==========
Asterisk is an open source implementation of a telephone private branch
exchange (PBX).
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-misc/asterisk < 1.0.11_p1 >= 1.0.11_p1
Description
===========
Asterisk fails to properly check the length of truncated video frames
in the IAX2 channel driver which results in a buffer overflow.
Impact
======
An attacker could exploit this vulnerability by sending a specially
crafted IAX2 video stream resulting in the execution of arbitrary code
with the permissions of the user running Asterisk.
Workaround
==========
Disable public IAX2 support.
Resolution
==========
All Asterisk users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/asterisk-1.0.11_p1"
