Red Hat Security Advisory 2012-0478-01
Posted Apr 13, 2012
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2012-0478-01 - Samba is an open-source implementation of the Server Message Block or Common Internet File System 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 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 to crash or, possibly, execute arbitrary code with the privileges of the root user.

3. Description:

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.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
