The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2011-1220 advisory.

    - Security Release, add fix for CVE-2011-2724
    - Security Release, fixes CVE-2011-2694, CVE-2011-2522, CVE-2011-1678

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Updated samba3x packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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, provided by the Samba rebase in RHBA-2011:0054, 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 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.

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.

This is an update that fixes a problem with handling embedded newlines in share names or mountpoints.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Updated samba and cifs-utils packages that fix multiple security issues and one bug are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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.

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.

Multiple vulnerabilities has been discovered and corrected in samba/cifs-utils :

smbfs in Samba 3.5.8 and earlier attempts to use (1) mount.cifs to append to the /etc/mtab file and (2) umount.cifs to append to the /etc/mtab.tmp file without first checking whether resource limits would interfere, which allows local users to trigger corruption of the /etc/mtab file via a process with a small RLIMIT_FSIZE value, a related issue to CVE-2011-1089 (CVE-2011-1678).

The check_mtab function in client/mount.cifs.c in mount.cifs in smbfs in Samba 3.5.10 and earlier does not properly verify that the (1) device name and (2) mountpoint strings are composed of valid characters, which allows local users to cause a denial of service (mtab corruption) via a crafted string. NOTE: this vulnerability exists because of an incorrect fix for CVE-2010-0547 (CVE-2011-2724).

Additionally for Mandriva Linux 2010.2 the cifs-utils package has been upgraded to the 4.8.1 version that brings numerous additional fixes.

Packages for 2009.0 are provided as of the Extended Maintenance Program. Please visit this link to learn more:
http://store.mandriva.com/product_info.php?cPath=149 products_id=490

The updated packages have been patched to correct these issues.

Dan Rosenberg discovered that Samba incorrectly handled changes to the mtab file. A local attacker could use this issue to corrupt the mtab file, possibly leading to a denial of service. (CVE-2011-1678)

Jan Lieskovsky discovered that Samba incorrectly filtered certain strings being added to the mtab file. A local attacker could use this issue to corrupt the mtab file, possibly leading to a denial of service. This issue only affected Ubuntu 10.04 LTS. (CVE-2011-2724)

Dan Rosenberg discovered that Samba incorrectly handled the mtab lock file. A local attacker could use this issue to create a stale lock file, possibly leading to a denial of service. (CVE-2011-3585).

The remote host is affected by the vulnerability described in GLSA-201206-22 (Samba: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Samba. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could possibly execute arbitrary code with root       privileges, cause a Denial of Service condition, take ownership of shared       files, or bypass file permissions. Furthermore, a local attacker may be       able to cause a Denial of Service condition or obtain sensitive       information in a Samba credentials file.
  Workaround :

    There is no known workaround at this time.
