Samba is a suite of programs used by machines to share files, printers, and
other information.

A flaw was found in the way Samba handled file descriptors. If an attacker
were able to open a large number of file descriptors on the Samba server,
they could flip certain stack bits to “1” values, resulting in the Samba
server (smbd) crashing. (CVE-2011-0719)

Red Hat would like to thank the Samba team for reporting this issue.

Users of Samba are advised to upgrade to these updated packages, which
contain a backported patch to resolve this issue. After installing this
update, the smb service will be restarted automatically.
