Título:	RedHat Security Advisory RHSA-2011:1221
Resumen:	NOSUMMARY
Descripción:	Description: The remote host is missing updates announced in advisory RHSA-2011:1221. Samba is a suite of programs used by machines to share files, printers, and other information. The cifs-utils package contains utilities for mounting and managing CIFS (Common Internet File System) shares. 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. (CVE-2011-2694) 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, provided in the cifs-utils package included in the GA release of Red Hat Enterprise Linux 6, 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 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 cifs-utils package distributed by Red Hat does not have the setuid bit set. We recommend that administrators do not manually set the setuid bit for mount.cifs. Red Hat would like to thank the Samba project for reporting CVE-2011-2694 and CVE-2011-2522, and Dan Rosenberg for reporting CVE-2011-1678. Upstream acknowledges Nobuhiro Tsuji of NTT DATA Security Corporation as the original reporter of CVE-2011-2694, and Yoshihiro Ishikawa of LAC Co., Ltd. as the original reporter of CVE-2011-2522. This update also fixes the following bug: * If plain text passwords were used (encrypt passwords = no in /etc/samba/smb.conf), Samba clients running the Windows XP or Windows Server 2003 operating system may not have been able to access Samba shares after installing the Microsoft Security Bulletin MS11-043. This update corrects this issue, allowing such clients to use plain text passwords to access Samba shares. (BZ#728517) Users of samba and cifs-utils 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. Solution: Please note that this update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date http://rhn.redhat.com/errata/RHSA-2011-1221.html Risk factor : High CVSS Score: 6.8
