Description |
| 39 |
=========== |
| 40 |
|
| 41 |
aspell includes a utility for handling wordlists called |
| 42 |
word-list-compress. This utility fails to do proper bounds checking |
| 43 |
when processing words longer than 256 bytes. |
| 44 |
|
| 45 |
Impact |
| 46 |
====== |
| 47 |
|
| 48 |
If an attacker could entice a user to handle a wordlist containing very |
| 49 |
long word lengths it could result in the execution of arbitrary code |
| 50 |
with the permissions of the user running the program. |
| 51 |
|
| 52 |
Workaround |
| 53 |
========== |
| 54 |
|
| 55 |
There is no known workaround at this time. All users are encouraged to |
| 56 |
upgrade to the latest available version. |
| 57 |
|
| 58 |
Resolution |
| 59 |
========== |
| 60 |
|
| 61 |
All users should upgrade to the latest available version of aspell. |
