Samba 3.x before 3.3.15, 3.4.x before 3.4.12, and 3.5.x before 3.5.7 does
not perform range checks for file descriptors before use of the FD_SET
macro, which allows remote attackers to cause a denial of service (stack
memory corruption, and infinite loop or daemon crash) by opening a large
number of files, related to (1) Winbind or (2) smbd.
