-Subject: [PATCH] Fix denial of service - memory corruption.
-
-CVE-2011-0719
-
-Fix bug #7949 (DoS in Winbind and smbd with many file descriptors open).
-
-All current released versions of Samba are vulnerable to
-a denial of service caused by memory corruption. Range
-checks on file descriptors being used in the FD_SET macro
-were not present allowing stack corruption. This can cause
-the Samba code to crash or to loop attempting to select
-on a bad file descriptor set.
-
-A connection to a file share, or a local account is needed
-to exploit this problem, either authenticated or unauthenticated
-(guest connection).
-
-Currently we do not believe this flaw is exploitable
-beyond a crash or causing the code to loop, but on the
-advice of our security reviewers we are releasing fixes
-in case an exploit is discovered at a later date.
