Scientific Linux Security Update : samba3x on SL5.x i386/x86_64

This script is Copyright (C) 2012-2014 Tenable Network Security, Inc.

Synopsis :

The remote Scientific Linux host is missing one or more security

Description :

Samba is a suite of programs used by machines to share files,
printers, and other information.

A cross-site scripting (XSS) flaw was found in the password change
page of the Samba Web Administration Tool (SWAT). If a remote attacker
could trick a user, who was logged into the SWAT interface, into
visiting a specially crafted URL, it would lead to arbitrary web
script execution in the context of the user's SWAT session.

It was found that SWAT web pages did not protect against Cross-Site
Request Forgery (CSRF) attacks. If a remote attacker could trick a
user, who was logged into the SWAT interface, into visiting a
specially crafted URL, the attacker could perform Samba configuration
changes with the privileges of the logged in user. (CVE-2011-2522)

It was found that the fix for CVE-2010-0547 was incomplete. The
mount.cifs tool did not properly handle share or directory names
containing a newline character, allowing a local attacker to corrupt
the mtab (mounted file systems table) file via a specially crafted
CIFS (Common Internet File System) share mount request, if mount.cifs
had the setuid bit set. (CVE-2011-2724)

It was found that the mount.cifs tool did not handle certain errors
correctly when updating the mtab file. If mount.cifs had the setuid
bit set, a local attacker could corrupt the mtab file by setting a
small file size limit before running mount.cifs. (CVE-2011-1678)

Note: mount.cifs from the samba3x packages distributed by Scientific
Linux does not have the setuid bit set. We recommend that
administrators do not manually set the setuid bit for mount.cifs.

Users of Samba are advised to upgrade to these updated packages, which
contain backported patches to resolve these issues. After installing
this update, the smb service will be restarted automatically.
