Synopsis: Critical: samba security update
Issue Date: 2012-02-23
CVE Numbers: CVE-2012-0870

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

An input validation flaw was found in the way Samba handled Any Batched
(AndX) requests. A remote, unauthenticated attacker could send a
specially-crafted SMB packet to the Samba server, possibly resulting in
arbitrary code execution with the privileges of the Samba server (root).
(CVE-2012-0870)

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.
