Synopsis

Critical: samba security update

Type/Severity

Security Advisory: Critical

Topic

Updated samba packages that fix one security issue are now available for
Red Hat Enterprise Linux 4 Extended Life Cycle 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.

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.
