"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.

This vulnerability has been fixed in samba version 2.2.7, and the
updated packages have had a patch applied to fix the problem."
