RHEL 4 / 5 : samba (RHSA-2009:1529)
medium Nessus Plugin ID 42286
Synopsis
The remote Red Hat host is missing one or more security updates.Description
Updated samba packages that fix multiple security issues are now available for Red Hat Enterprise Linux 4 and 5.This update has been rated as having moderate security impact by the Red Hat Security Response Team.
Samba is a suite of programs used by machines to share files, printers, and other information.
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 samba 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)
Users of Samba should upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, the smb service will be restarted automatically.
