<affected>
<package name="net-misc/kiax" auto="yes" arch="*">
<unaffected range="ge">0.8.5_p1</unaffected>

<background>
<p>
Kiax is a graphical softphone supporting the IAX protocol (Inter
Asterisk eXchange), which allows PC users to make VoIP calls to
Asterisk servers.

<description>
<p>
The iax_net_read function in the iaxclient library fails to properly
handle IAX2 packets with truncated full frames or mini-frames. These
frames are detected in a length check but processed anyway, leading to
buffer overflows.
</p>
</description>
<impact type="normal">
<p>
By sending a specially crafted IAX2 packet, an attacker could execute
arbitrary code with the permissions of the user running Kiax.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Kiax users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=net-misc/kiax-0.8.5_p1"</code>
</resolution>
