<description>
|
||
<p>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.
|
||
</p>
|
||
</description>
|
||
<impact type="normal">
|
||
<p>An authenticated remote attacker could possibly execute arbitrary code
|
||
with the privileges of the process, or cause a Denial of Service
|
||
condition.
|
||
</p>
|
||
</impact>
|
||
<workaround>
|
||
<p>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.
|
||
</p>
|
||
</workaround>
|
||
<resolution>
|
||
<p>All Roundcube users should upgrade to the latest version:</p>
|
||
|
||
<code>
|
||
# emerge --sync
|
||
# emerge --ask --oneshot --verbose ">=mail-client/roundcube-1.2.3"
|
||
</code>
