+  <description>
+    <p>
+    Victor Stinner reported an integer overflow in the
+    exif_data_load_data_entry() function from file exif-data.c while
+    handling Exif data.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    An attacker could entice a user to process a file with specially
+    crafted Exif extensions with an application making use of libexif,
+    which will trigger the integer overflow and potentially execute
+    arbitrary code or crash the application.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All libexif users should upgrade to the latest version. Please note
+    that users upgrading from "&lt;=media-libs/libexif-0.6.13" should also run
+    revdep-rebuild after their upgrade.
+    </p>
