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
