Synopsis
========

A vulnerability in Chora allows remote code execution and file upload.

Background
==========

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

Affected packages
=================

    -------------------------------------------------------------------
     Package              /   Vulnerable   /                Unaffected
    -------------------------------------------------------------------
  1  net-www/horde-chora        < 1.2.2                       >= 1.2.2

Description
===========

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.

Impact
======

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.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All users are advised to upgrade to the latest version of Chora:

    # emerge sync

    # emerge -pv ">=net-www/horde-chora-1.2.2"
    # emerge ">=net-www/horde-chora-1.2.2"
