    libexif is a library for parsing, editing and saving EXIF data.
    </p>
  </background>
  <description>
    <p>
    libexif contains a buffer overflow vulnerability in the EXIF tag
    validation code. When opening an image with a specially crafted EXIF
    tag, the lack of validation can cause applications linked to libexif to
    crash.
    </p>
  </description>
  <impact type="normal">
    <p>
    A specially crafted EXIF file could crash applications making use
    of libexif, potentially allowing the 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 libexif users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=media-libs/libexif-0.5.12-r1&quot;</code>
  </resolution>
