The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-201612-44
(Roundcube: Arbitrary code execution)
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.
An authenticated remote attacker could possibly execute arbitrary code
with the privileges of the process, or cause a Denial of Service
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.

All Roundcube users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=mail-client/roundcube-1.2.3'

Medium / CVSS Base Score : 6.0
