+  <title>libexif: Buffer overflow</title>
+  <synopsis>
+    libexif does not properly handle image EXIF information, possibly allowing
+    for the execution of arbitrary code.

+  <affected>
+    <package name="media-libs/libexif" auto="yes" arch="*">
+      <unaffected range="ge">0.6.16</unaffected>

+  <background>
+    <p>
+    libexif is a library for parsing, editing and saving EXIF metadata from
+    images.
+    </p>
+  </background>
+  <description>
+    <p>
+    iDefense Labs have discovered that the exif_data_load_data_entry()
+    function in libexif/exif-data.c improperly handles integer data while
+    working with an image with many EXIF components, allowing an integer
+    overflow possibly leading to a heap-based buffer overflow.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    An attacker could entice a user of an application making use of a
+    vulnerable version of libexif to load a specially crafted image file,
+    possibly resulting in a crash of the application or the execution of
+    arbitrary code with the rights of the user running 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:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=media-libs/libexif-0.6.16&quot;</code>
