WeeChat: Multiple vulnerabilities

WeeChat: Multiple vulnerabilities Two vulnerabilities have been found in WeeChat, the worst of which may allow execution of arbitrary code. weechat May 03, 2014 May 03, 2014: 1 442600 remote 0.3.9.2 0.3.9.2

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

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).

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.

There is no known workaround at this time.

All WeeChat users should upgrade to the latest version:


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