+  <title>Feynmf: Insecure temporary file creation</title>
+  <synopsis>
+    A vulnerability has been discovered in Feynmf allowing local users to
+    overwrite arbitrary files via a symlink attack.

+    Kevin B. McCarty discovered that the feynmf.pl script creates a
+    temporary "properly list" file at the location "$TMPDIR/feynmf$PID.pl",
+    where $PID is the process ID.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    A local attacker could create symbolic links in the directory where the
+    temporary files are written, pointing to a valid file somewhere on the
+    filesystem that is writable by the user running Feynmf. When Feynmf
+    writes the temporary file, the target valid file would then be
+    overwritten with the contents of the Feynmf temporary file.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All Feynmf users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=dev-tex/feynmf-1.08-r2&quot;</code>
