Security Advisory: Critical
Updated samba3x packages that fix one security issue are now available for
Red Hat Enterprise Linux 5.
The Red Hat Security Response Team has rated this update as having critical
security impact. A Common Vulnerability Scoring System (CVSS) base score,

the References section.
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)
Users of Samba are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. After installing this
update, the smb service will be restarted automatically.
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
