+    Drake Wilson reported that the hack-local-variables() function in GNU
+    Emacs 22 does not properly match assignments of local variables in a
+    file against a list of unsafe or risky variables, allowing to override
+    them (CVE-2007-5795). Andreas Schwab (SUSE) discovered a stack-based
+    buffer overflow in the format function when handling values with high
+    precision (CVE-2007-6109).

+  <impact type="normal">
+    <p>
+    Remote attackers could entice a user to open a specially crafted file
+    in GNU Emacs, possibly leading to the execution of arbitrary Emacs Lisp
+    code (via CVE-2007-5795) or arbitrary code (via CVE-2007-6109) with the
+    privileges of the user running GNU Emacs.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    The first vulnerability can be worked around by setting the
+    "enable-local-variables" option to "nil", disabling the processing of
+    local variable lists. GNU Emacs prior to version 22 is not affected by
+    this vulnerability. There is no known workaround for the second
+    vulnerability at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All GNU Emacs users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=app-editors/emacs-22.1-r3&quot;</code>
