Synopsis
=======

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

Background
=========

aspell is a popular spell-checker. Dictionaries are available for many languages.

Affected packages
================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-text/aspell <= 0.50.5-r1 >= 0.50.5-r2

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.

# emerge sync

# emerge -pv ">=app-text/aspell-0.50.5-r2"
# emerge ">=app-text/aspell-0.50.5-r2"
