Vulnerability Information

Severity: Critical
Vulnerability Published: 2012-04-10
Patch Published: 2012-04-10
CVE [?]: CVE-2012-1182
CPE [?]: cpe:/o:centos:centos:5, p-cpe:/a:centos:centos:samba3x, p-cpe:/a:centos:centos:samba3x-client, p-cpe:/a:centos:centos:samba3x-common, p-cpe:/a:centos:centos:samba3x-doc, p-cpe:/a:centos:centos:samba3x-domainjoin-gui, p-cpe:/a:centos:centos:samba3x-swat, p-cpe:/a:centos:centos:samba3x-winbind, p-cpe:/a:centos:centos:samba3x-winbind-devel

Synopsis

The remote CentOS host is missing one or more security updates.

Description

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.

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.

Solution

Update the affected samba3x packages.
