+  <title>file: Integer underflow</title>
+  <synopsis>
+    A buffer underflow vulnerability has been reported in file allowing for the
+    user-assisted execution of arbitrary code.

+  <background>
+    <p>
+    file is a utility that guesses a file format by scanning binary data
+    for patterns.

+    Jean-Sebastien Guay-Leroux reported an integer underflow in
+    file_printf function.
+    </p>
+  </description>
+  <impact type="high">
+    <p>
+    A remote attacker could entice a user to run the "file" program on a
+    specially crafted file that would trigger a heap-based buffer overflow
+    possibly leading to the execution of arbitrary code with the rights of
+    the user running "file". Note that this vulnerability could be also
+    triggered through an automatic file scanner like amavisd-new.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    Since file is a system package, all Gentoo users should upgrade to the
+    latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=sys-apps/file-4.20&quot;</code>
+  </resolution>
