+ <background>
+ <p>
+ Chora is a PHP-based SVN/CVS repository viewer by the HORDE project.
+ </p>
+ </background>
+ <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>
