A flaw was found in Samba. Some SMB1 write requests were not correctly
range-checked to ensure the client had sent enough data to fulfill the
write, allowing server memory contents to be written into the file (or
printer) instead of client-supplied data. The client cannot control the
area of the server memory written to the file (or printer).
