<description>
|
|
<p>
|
|
Asterisk fails to properly check the length of truncated video frames
|
|
in the IAX2 channel driver which results in a buffer overflow.
|
|
</p>
|
|
</description>
|
|
<impact type="high">
|
|
<p>
|
|
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.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
Disable public IAX2 support.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Asterisk users should upgrade to the latest version:
|
|

|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-misc/asterisk-1.0.11_p1"</code>
