  <description>
    <p>
    aspell includes a utility for handling wordlists called
    word-list-compress. This utility fails to do proper bounds checking
    when processing words longer than 256 bytes.
    </p>
  </description>
  <impact type="normal">
    <p>
    If an attacker could entice a user to handle a wordlist containing very
    long word lengths it could result in the execution of arbitrary code
    with the permissions of the user running the program.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time. All users are encouraged to
    upgrade to the latest available version.
    </p>
  </workaround>
  <resolution>
    <p>
    All users should upgrade to the latest available version of aspell.
