+    Frank Sheiness discovered that the mime8to7() function can recurse
+    endlessly during the decoding of multipart MIME messages until the
+    stack of the process is filled and the process crashes.

+  <impact type="normal">
+    <p>
+    By sending specially crafted multipart MIME messages, a remote
+    attacker can cause a subprocess forked by Sendmail to crash. If
+    Sendmail is not set to use a randomized queue processing, the attack
+    will effectively halt the delivery of queued mails as well as the
+    malformed one, incoming mail delivered interactively is not affected.
+    Additionally, on systems where core dumps with an individual naming
+    scheme (like "core.pid") are enabled, a filesystem may fill up with
+    core dumps. Core dumps are disabled by default in Gentoo.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    The Sendmail 8.13.7 release information offers some workarounds, please
+    see the Reference below. Note that the issue has actually been fixed in
+    the 8.13.6-r1 ebuild.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All Sendmail users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=mail-mta/sendmail-8.13.6-r1&quot;</code>
