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>

<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.

<resolution>
|

|
<p>
|

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