Advisory URL: https://rhn.redhat.com/errata/RHSA-2007-0061.html
Issue date: 2007-03-14
Updated on: 2007-03-14
Product: Red Hat Enterprise Linux
CVE Names: CVE-2007-0452
- ---------------------------------------------------------------------

1. Summary:

Updated samba packages that fix a denial of service vulnerability are now
available for Red Hat Enterprise Linux 5.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64

3. Problem description:

Samba provides file and printer sharing services to SMB/CIFS clients.

A denial of service flaw was found in Samba's smbd daemon process. An
authenticated user could send a specially crafted request which would cause
a smbd child process to enter an infinite loop condition. By opening
multiple CIFS sessions, an attacker could exhaust system resources
(CVE-2007-0452).

Users of Samba should update to these packages, which contain a
backported patch to correct this issue.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
