Scientific Linux Security Update : samba3x on SL5.x i386/x86_64
medium Nessus Plugin ID 61121
Language:
Synopsis
The remote Scientific Linux host is missing one or more security updates.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.
(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 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.
