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.
Changes ------- o Jeremy Allison * BUG 7949: Fix DoS in Winbind and smbd with many file descriptors open. ================ Download Details ================ The uncompressed tarballs and patch files have been signed using GnuPG (ID 6568B7EA).
