A vulnerability in samba versions 2.2.2 through 2.2.6 was discovered by the Debian samba maintainers. A bug in the length checking for encrypted password change requests from clients could be exploited using a buffer overrun attack on the smbd stack. This attack would have to crafted in such a way that converting a DOS codepage string to little endian UCS2 unicode would translate into an executable block of code.
