Synopsis
========

Multiple vulnerabilities have been found in Roundcube allowing remote
authenticated users to execute arbitrary code, inject arbitrary web
scripts, and perform cross-site scripting (XSS).

Background
==========

Free and open source webmail software for the masses, written in PHP.

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

——————————————————————-
Package / Vulnerable / Unaffected
——————————————————————-
1 mail-client/roundcube < 1.1.4 >= 1.1.4

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

Remote authenticated users with certain permissions can read arbitrary
files or possibly execute arbitrary code via .. in the _skin parameter
to index.php. Additionally, a cross-site scripting (XSS) vulnerability
in program/js/app.js allows remote authenticated users to inject
arbitrary web script or HTML via the file name in a drag-n-drop file
upload.

Impact
======

A remote authenticated user could possibly execute arbitrary code with
the privileges of the process, inject arbitrary web scripts or HTML,
read arbitrary files, or perform XSS.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Roundcube users should upgrade to the latest version:

# emerge –sync
# emerge –ask –oneshot –verbose “>=mail-client/roundcube-1.1.4”
