<title>Kiax: Arbitrary code execution</title>
A security vulnerability in the iaxclient library could lead to the
execution of arbitrary code by a remote attacker.

Kiax is a graphical softphone supporting the IAX protocol (Inter
Asterisk eXchange), which allows PC users to make VoIP calls to
Asterisk servers.
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.
<impact type="normal">
By sending a specially crafted IAX2 packet, an attacker could execute
arbitrary code with the permissions of the user running Kiax.
There is no known workaround at this time.
All Kiax users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-misc/kiax-0.8.5_p1&quot;</code>
