Gentoo Linux Security Advisory GLSA 200606-30

                                        http://security.gentoo.org/

Severity: Normal
Title: Kiax: Arbitrary code execution
Date: June 30, 2006
Bugs: #136099
ID: 200606-30

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 &quot;&gt;=net-misc/kiax-0.8.5_p1&quot;
