- From 2.2.7 release notes: |
| 16 |
|
| 17 |
There was a bug in the length checking for encrypted password change |
| 18 |
requests from clients. A client could potentially send an encrypted |
| 19 |
password, which, when decrypted with the old hashed password could be |
| 20 |
used as a buffer overrun attack on the stack of smbd. The attach would |
| 21 |
have to be crafted such that converting a DOS codepage string to little |
| 22 |
endian UCS2 unicode would translate into an executable block of code. |
