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"
