Synopsis
========
Two vulnerabilities have been found in WeeChat, the worst of which may
allow execution of arbitrary code.

Background
==========
Wee Enhanced Environment for Chat (WeeChat) is a light and extensible
console IRC client.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-irc/weechat < 0.3.9.2 >= 0.3.9.2

Description
===========
Two vulnerabilities have been discovered in WeeChat:

* The hook_process() function does not properly handle shell expansions
(CVE-2012-5534).
* WeeChat does not properly decode colors which could cause a
heap-based buffer overflow (CVE-2012-5854).

Impact
======
A remote attacker could entice a user to open a specially crafted
script or send messages with specially crafted colors, possibly
resulting in execution of arbitrary code with the privileges of the
process, or a Denial of Service condition.

Workaround
==========
There is no known workaround at this time.

Resolution
==========
All WeeChat users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-irc/weechat-0.3.9.2"
