CentOS Errata and Security Advisory CESA-2012:0465
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 flaw in the Samba suite’s Perl-based DCE/RPC IDL (PIDL) compiler, used
to generate code to handle RPC calls, resulted in multiple buffer overflows
in Samba. A remote, unauthenticated attacker could send a specially-crafted
RPC request that would cause the Samba daemon (smbd) to crash or, possibly,
execute arbitrary code with the privileges of the root user.
(CVE-2012-1182)
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.
