+    Mark Richters discovered a buffer overflow in the open_sty() function
+    in file mkind.c. Other vulnerabilities have also been discovered in the
+    same file but might not be exploitable (CVE-2007-0650). Tetex also
+    includes vulnerable code from GD library (GLSA 200708-05), and from
+    Xpdf (CVE-2007-3387).

+  <impact type="normal">
+    <p>
+    A remote attacker could entice a user to process a specially crafted
+    PNG, GIF or PDF file, or to execute "makeindex" on an overly long
+    filename. In both cases, this could lead to the remote execution of
+    arbitrary code with the privileges of the user running the application.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All teTeX users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose "&gt;=app-text/tetex-3.0_p1-r4"</code>
