Severity: Normal
Title: Roundcube: Arbitrary code execution
Date: December 24, 2016
Bugs: #601410
ID: 201612-44

Synopsis
========

A vulnerability in Roundcube could potentially lead to arbitrary code
execution.

Background
==========

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

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

——————————————————————-
Package / Vulnerable / Unaffected
——————————————————————-
1 mail-client/roundcube < 1.2.3 >= 1.2.3

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

Roundcube, when no SMTP server is configured and the sendmail program
is enabled, does not properly restrict the use of custom envelope-from
addresses on the sendmail command line.

Impact
======

An authenticated remote attacker could possibly execute arbitrary code
with the privileges of the process, or cause a Denial of Service
condition.

Workaround
==========

Don’t use a MTA (Mail Transfer Agent) in conjunction with Roundcube
which implements sendmail’s “-O” or “-X” parameter, or configure
Roundcube to use a SMTP server as recommended by upstream.

Resolution
==========

All Roundcube users should upgrade to the latest version:

# emerge –sync
# emerge –ask –oneshot –verbose “>=mail-client/roundcube-1.2.3”

References
