CentOS Errata and Security Advisory CESA-2014:1008
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 heap-based buffer overflow flaw was found in Samba’s NetBIOS message
block daemon (nmbd). An attacker on the local network could use this flaw
to send specially crafted packets that, when processed by nmbd, could
possibly lead to arbitrary code execution with root privileges.
(CVE-2014-3560)
This update also fixes the following bug:
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.
