+  <title>tiff: Buffer overflows in image decoding</title>
+  <synopsis>
+    Multiple heap-based overflows have been found in the tiff library image
+    decoding routines, potentially allowing to execute arbitrary code with the
+    rights of the user viewing a malicious image.

+    The tiff library contains encoding and decoding routines for the Tag Image
+    File Format. It is called by numerous programs, including GNOME and KDE, to
+    help in displaying TIFF images. xv is a multi-format image manipulation
+    utility that is statically linked to the tiff library.

+    Chris Evans found heap-based overflows in RLE decoding routines in
+    tif_next.c, tif_thunder.c and potentially tif_luv.c.

+  <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 GNOME and KDE 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 -pv ">=media-libs/tiff-3.6.1-r2"
+    # emerge ">=media-libs/tiff-3.6.1-r2"</code>
+    <p>
+    xv makes use of the tiff library and needs to be recompiled to receive the
+    new patched version of the library. All xv users should also upgrade to the
+    latest version:
+    </p>
+    <code>
+    # emerge sync
+
+    # emerge -pv ">=media-gfx/xv-3.10a-r8"
+    # emerge ">=media-gfx/xv-3.10a-r8"</code>
