Severity:	normal
Title:	WeeChat: Multiple vulnerabilities
Date:	05/03/2014
Bugs:	#442600
ID:	201405-03

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	Architecture(s)
net-irc/weechat	< 0.3.9.2	>= 0.3.9.2	All supported architectures

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"
