<p>Wee Enhanced Environment for Chat (WeeChat) is a light and extensible
console IRC client.
<p>Two vulnerabilities have been discovered in WeeChat:</p>
<li>The hook_process() function does not properly handle shell expansions
<li>WeeChat does not properly decode colors which could cause a
heap-based buffer overflow (CVE-2012-5854).
<impact type="normal">
<p>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.
<p>There is no known workaround at this time.</p>
<p>All WeeChat users should upgrade to the latest version:</p>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=net-irc/weechat-"
