Synopsis
========
A security vulnerability in the iaxclient library could lead to the
execution of arbitrary code by a remote attacker.
Background
==========
Kiax is a graphical softphone supporting the IAX protocol (Inter
Asterisk eXchange), which allows PC users to make VoIP calls to
Asterisk servers.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-misc/kiax < 0.8.5_p1 >= 0.8.5_p1
Description
===========
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
======
By sending a specially crafted IAX2 packet, an attacker could execute
arbitrary code with the permissions of the user running Kiax.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Kiax users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/kiax-0.8.5_p1"
