The remote MiracleLinux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2012-264:01 advisory.

    Samba is the suite of programs by which a lot of PC-related machines share files, printers, and other     information (such as lists of available files and printers). The Windows NT, OS/2, and Linux operating     systems support this natively, and add-on packages can enable the same thing for DOS, Windows, VMS, UNIX     of all kinds, MVS, and more. This package provides an SMB server that can be used to provide network     services to SMB (sometimes called Lan Manager) clients. Samba uses NetBIOS over TCP/IP (NetBT) protocols     and does NOT need the NetBEUI (Microsoft Raw NetBIOS frame) protocol.
    Security issues fixed with this release:
    CVE-2010-0926     The default configuration of smbd in Samba before 3.3.11, 3.4.x before 3.4.6, and 3.5.x before 3.5.0rc3,     when a writable share exists, allows remote authenticated users to leverage a directory traversal     vulnerability, and access arbitrary files, by using the symlink command in smbclient to create a symlink     containing .. (dot dot) sequences, related to the combination of the unix extensions and wide links     options.
    CVE-2012-0870     Heap-based buffer overflow in process.c in smbd in Samba 3.0, as used in the file-sharing service on the     BlackBerry PlayBook tablet before 2.0.0.7971 and other products, allows remote attackers to cause a denial     of service (daemon crash) or possibly execute arbitrary code via a Batched (aka AndX) request that     triggers infinite recursion.
    Fixed bugs:
     Because the smbclient sometimes failed to return the proper exit status code, using it in a script could     cause the script to fail. This has been fixed.
    Enhancement:
     Added support for Windows Server 2008 R2 domains.

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

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

The version of Samba running on the remote host is prior to 3.4.0. It is, therefore, affected by a remote code execution vulnerability in process.c due to a heap-based buffer overflow.  An unauthenticated, remote attacker can exploit this to bypass authentication and execute arbitrary commands via Batched / AndX request.

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

The remote host is running a version of Mac OS X 10.6 that does not have Security Update 2012-002 applied. This update contains multiple security-related fixes for the following components :

  - curl
  - Directory Service
  - ImageIO
  - libarchive
  - libsecurity
  - libxml
  - Quartz Composer
  - QuickTime
  - Ruby
  - Samba
  - Security Framework

- Add the ldapsmb sources as else patches against them     have no chance to apply.

  - Samba pre-3.6.4 are affected by a vulnerability that     allows remote code exe- cution as the 'root' user; PIDL     based autogenerated code allows overwriting beyond of     allocated array; CVE-2012-1182; (bso#8815);
    (bnc#752797).

  - s3-winbindd: Only use SamLogonEx when we can get     unencrypted session keys; (bso#8599).

  - Correctly handle DENY ACEs when privileges apply;
    (bso#8797).

  - s3:smb2_server: fix a logic error, we should sign non     guest sessions; (bso8749).

  - Allow vfs_aio_pthread to build as a static module;
    (bso#8723).

  - s3:dbwrap_ctdb: return the number of records in     db_ctdb_traverse() for persistent dbs; (#bso8527).

  - s3: segfault in dom_sid_compare(bso#8567).

  - Honor SeTakeOwnershiPrivilege when client asks for     SEC_STD_WRITE_OWNER; (bso#8768).

  - s3-winbindd: Close netlogon connection if the status     returned by the NetrSamLogonEx call is timeout in the     pam_auth_crap path; (bso#8771).

  - s3-winbindd: set the can_do_validation6 also for trusted     domain; (bso#8599).

  - Fix problem when calculating the share security mask,     take priviliges into account for the connecting user;
    (bso#8784).

  - Fix crash in dcerpc_lsa_lookup_sids_noalloc() with over     1000 groups; (bso#8807); (bnc#751454).

  - Remove obsoleted Authors lines from spec file for     post-11.2 systems.

  - Make ldapsmb build with Fedora 15 and 16; (bso#8783).

  - BuildRequire libuuid-devel for post-11.0 and other     systems.

  - Define missing python macros for non SUSE systems.

  - PreReq to fillup_prereq and insserv_prereq only on SUSE     systems.

  - Always use cifstab instead of smbfstab on non SUSE     systems.

  - Ensure AndX offsets are increasing strictly     monotonically in pre-3.4 versions; CVE-2012-0870;
    (bnc#747934).

  - Add SERVERID_UNIQUE_ID_NOT_TO_VERIFY; (bso#8760);
    (bnc#741854).

  - s3-printing: fix crash in printer_list_set_printer();
    (bso#8762); (bnc#746825).

The remote Samba install is prone to a heap-based buffer overflow attack.

An attacker can exploit this issue to execute arbitrary code with the privileges of the application. Failed exploit attempts will result in a denial of service condition.

Updated samba packages that fix one security issue are now available for Red Hat Enterprise Linux 4 and 5, and Red Hat Enterprise Linux 5.3 Long Life, and 5.6 Extended Update Support.

The Red Hat Security Response Team has rated this update as having critical security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

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

An input validation flaw was found in the way Samba handled Any Batched (AndX) requests. A remote, unauthenticated attacker could send a specially crafted SMB packet to the Samba server, possibly resulting in arbitrary code execution with the privileges of the Samba server (root). (CVE-2012-0870)

Red Hat would like to thank the Samba team for reporting this issue.
Upstream acknowledges Andy Davis of NGS Secure as the original reporter.

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

Andy Davis discovered that Samba incorrectly handled certain AndX offsets. A remote attacker could send a specially crafted request to the server and cause a denial of service, or possibly execute arbitrary code.

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

This update of Samba fixes a heap-based buffer overflow that could be exploited by remote, unauthenticated attackers to crash the smbd daemon or potentially execute arbitrary code via specially crafted SMB AndX request packets. (CVE-2012-0870)

Also fixed two non security bugs :

  - Fix to handle domain join using NetBIOS name;.
    (bnc#633729)

  - Fixed the DFS referral response for msdfs root;.
    (bnc#703655)
