Samba is an open-source implementation of the Server Message Block (SMB) or
Common Internet File System (CIFS) protocol, which allows PC-compatible
machines to share files, printers, and other information.
A denial of service flaw was found in the way the sys_recvfile() function
of nmbd, the NetBIOS message block daemon, processed non-blocking sockets.
An attacker could send a specially crafted packet that, when processed,
would cause nmbd to enter an infinite loop and consume an excessive amount
of CPU time. (CVE-2014-0244)
It was discovered that smbd, the Samba file server daemon, did not properly
handle certain files that were stored on the disk and used a valid Unicode
character in the file name. An attacker able to send an authenticated
non-Unicode request that attempted to read such a file could cause smbd to
crash. (CVE-2014-3493)
Red Hat would like to thank Daniel Berteaud of FIREWALL-SERVICES SARL for
reporting CVE-2014-0244, and the Samba project for reporting CVE-2014-3493.
The Samba project acknowledges Simon Arlott as the original reporter of
CVE-2014-3493.
All Samba users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. After installing this
update, the smb service will be restarted automatically.
