word-list-compress. This utility fails to do proper bounds checking
when processing words longer than 256 bytes.

<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.

<workaround>
<p>
There is no known workaround at this time. All users are encouraged to
upgrade to the latest available version.
