  <title>giflib: Multiple vulnerabilities</title>
  <synopsis>
    giflib may dereference NULL or write out of bounds when processing
    malformed images, potentially resulting in Denial of Service or arbitrary
    code execution.

  <background>
    <p>
    giflib is a library for reading and writing GIF images.
    </p>

  <description>
    <p>
    Chris Evans and Daniel Eisenbud independently discovered two
    out-of-bounds memory write operations and a NULL pointer dereference in
    giflib.
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could craft a malicious GIF image and entice users to
    load it using an application making use of the giflib library,
    resulting in an application crash or potentially the execution of
    arbitrary code.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All giflib users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=media-libs/giflib-4.1.4"</code>
  </resolution>
