Synopsis
Critical: samba security and bug fix update
Type/Severity
Security Advisory: Critical
Topic
Updated samba packages that fix one security issue and one bug are now
available for Red Hat Enterprise Linux 3, 4, and 5, and Red Hat Enterprise
Linux 4.7, 5.3, and 5.4 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.
Description
Samba is a suite of programs used by machines to share files, printers, and
other information.
A missing array boundary checking flaw was found in the way Samba parsed
the binary representation of Windows security identifiers (SIDs). A
malicious client could send a specially-crafted SMB request to the Samba
server, resulting in arbitrary code execution with the privileges of the
Samba server (smbd). (CVE-2010-3069)
For Red Hat Enterprise Linux 4, this update also fixes the following bug:
- Previously, the restorecon utility was required during the installation
of the samba-common package. As a result, attempting to update samba
without this utility installed may have failed with the following error:
/var/tmp/rpm-tmp.[xxxxx]: line 7: restorecon: command not found
With this update, the utility is only used when it is already present on
the system, and the package is now always updated as expected. (BZ#629602)
Users of Samba are advised to upgrade to these updated packages, which
correct these issues. 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.
