GLSA 200606-30: Kiax: Arbitrary code execution

http://security.gentoo.org/

Severity:	normal
Title:	Kiax: Arbitrary code execution
Date:	06/30/2006
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	Architecture(s)
net-misc/kiax	< 0.8.5_p1	>= 0.8.5_p1	All supported architectures

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"
