Synopsis
Critical: samba security update
Type/Severity
Security Advisory: Critical
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
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.
Solution
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
