Chora is a PHP-based SVN/CVS repository viewer by the HORDE project.

<description>
<p>
A vulnerability in the diff viewer of Chora allows an attacker to inject
shellcode. An attacker can exploit PHP's file upload functionality to
upload a malicious binary to a vulnerable server, chmod it as executable,
and run the file.
</p>
</description>
<impact type="high">
<p>
An attacker could remotely execute arbitrary binaries with the permissions
of the PHP script, conceivably allowing further exploitation of local
vulnerabilities and remote root access.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All users are advised to upgrade to the latest version of Chora:
</p>
<code>
# emerge sync
# emerge -pv ">=www-apps/horde-chora-1.2.2"
# emerge ">=www-apps/horde-chora-1.2.2"</code>
