Samba 3.5.7, 3.4.12 and 3.3.15 Security Releases

Release Announcements
=====================

Samba 3.5.7, 3.4.12 and 3.3.15 are security releases in order to address CVE-2011-0719.


o  CVE-2011-0719:
   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.
