<description>
|
|
<p>Two vulnerabilities have been discovered in WeeChat:</p>
|
|
|
|
<ul>
|
|
<li>The hook_process() function does not properly handle shell expansions
|
|
(CVE-2012-5534).
|
|
</li>
|
|
<li>WeeChat does not properly decode colors which could cause a
|
|
heap-based buffer overflow (CVE-2012-5854).
|
|
</li>
|
|
</ul>
|
|
</description>
|
|
<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>
|
|
</impact>
|
|
<workaround>
|
|
<p>There is no known workaround at this time.</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>All WeeChat users should upgrade to the latest version:</p>
|

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

</code>
