Title:	Roundcube: Multiple Vulnerabilities
Date:	03/09/2016
Bugs:	#554866, #564476, #570336
ID:	201603-03

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	Architecture(s)
mail-client/roundcube	< 1.1.4	>= 1.1.4	All supported architectures

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”
