Samba mangling method buffer overflow
| samba-mangling-method-bo (16786) |  High Risk |
Description:
Samba is vulnerable to a buffer overflow in the mangling method = hash smb.conf option. A remote attacker could exploit this vulnerability to overflow a buffer and possibly execute arbitrary code on the system.
Note: The default setting for Samba 3, mangling method = hash2, is not vulnerable.
