Synopsis: Critical: samba3x security update

Advisory ID: RHSA-2012:0466-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-0466.html

Issue date: 2012-04-10

CVE Names: CVE-2012-1182

=====================================================================

 

1. Summary:

 

Updated samba3x packages that fix one security issue are now available for

Red Hat Enterprise Linux 5 and Red Hat Enterprise Linux 5.6 Extended Update

Support.

 

The Red Hat Security Response Team has rated this update as having critical

security impact. A Common Vulnerability Scoring System (CVSS) base score,

which gives a detailed severity rating, is available from the CVE link in

the References section.

 

2. Relevant releases/architectures:

 

RHEL Desktop Workstation (v. 5 client) - i386, x86_64

Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64

Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64

Red Hat Enterprise Linux EUS (v. 5.6 server) - i386, ia64, ppc, s390x, x86_64

 

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

https://access.redhat.com/knowledge/articles/11258
