Severity: High Title: Asterisk: IAX2 video frame buffer overflow Date: June 14, 2006 Bugs: #135680 ID: 200606-15

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"
