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"
