The remote host is missing updates announced in advisory RHSA-2009:1585. Samba is a suite of programs used by machines to share files, printers, and other information. These samba3x packages provide Samba 3.3, which is a Technology Preview for Red Hat Enterprise Linux 5. These packages cannot be installed in parallel with the samba packages. Note: Technology Previews are not intended for production use. A denial of service flaw was found in the Samba smbd daemon. An authenticated, remote user could send a specially-crafted response that would cause an smbd child process to enter an infinite loop. An authenticated, remote user could use this flaw to exhaust system resources by opening multiple CIFS sessions. (CVE-2009-2906) An uninitialized data access flaw was discovered in the smbd daemon when using the non-default dos filemode configuration option in smb.conf. An authenticated, remote user with write access to a file could possibly use this flaw to change an access control list for that file, even when such access should have been denied. (CVE-2009-1888) A flaw was discovered in the way Samba handled users without a home directory set in the back-end password database (e.g. /etc/passwd). If a share for the home directory of such a user was created (e.g. using the automated [homes] share), any user able to access that share could see the whole file system, possibly bypassing intended access restrictions. (CVE-2009-2813) The mount.cifs program printed CIFS passwords as part of its debug output when running in verbose mode. When mount.cifs had the setuid bit set, a local, unprivileged user could use this flaw to disclose passwords from a file that would otherwise be inaccessible to that user. Note: mount.cifs from the samba3x packages distributed by Red Hat does not have the setuid bit set. This flaw only affected systems where the setuid bit was manually set by an administrator. (CVE-2009-2948) These packages upgrade Samba from version 3.3.5 to version 3.3.8. Refer to the Samba Release Notes for a list of changes between versions: Users of samba3x should upgrade to these updated packages, which resolve these issues. After installing this update, the smb service will be restarted automatically.
