Synopsis
========

A bug in the aspell utility word-list-compress can allow an attacker to
execute arbitrary code.

Background
==========

Description
===========

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.

Impact
======

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
==========

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

Resolution
==========

All users should upgrade to the latest available version of aspell.
