+  <title>Roundcube: Arbitrary code execution</title>
+  <synopsis>A vulnerability in Roundcube could potentially lead to arbitrary
+    code execution.
+  </synopsis>

+  <affected>
+    <package name="mail-client/roundcube" auto="yes" arch="*">
+      <unaffected range="ge">1.2.3</unaffected>
+      <vulnerable range="lt">1.2.3</vulnerable>

+  <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 "&gt;=mail-client/roundcube-1.2.3"
+    </code>
