+  <title>tiff: New overflows in image decoding</title>
+  <synopsis>
+    An integer overflow has been found in the TIFF library image decoding
+    routines and the tiffdump utility, potentially allowing arbitrary code
+    execution.

+  <background>
+    <p>
+    The TIFF library contains encoding and decoding routines for the
+    Tag Image File Format. It is called by numerous programs, including
+    GNOME and KDE applications, to interpret TIFF images.

+    infamous41md found a potential integer overflow in the directory
+    entry count routines of the TIFF library (CAN-2004-1308). Dmitry V.
+    Levin found another similar issue in the tiffdump utility
+    (CAN-2004-1183).

+  <impact type="normal">
+    <p>
+    A remote attacker could entice a user to view a carefully crafted
+    TIFF image file, which would potentially lead to execution of arbitrary
+    code with the rights of the user viewing the image. This affects any
+    program that makes use of the TIFF library, including many web browsers
+    or mail readers.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All TIFF library users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose "&gt;=media-libs/tiff-3.7.1-r1"</code>
