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)

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.

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.

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 Redhat Enterprise Linux 4 / 5 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2012:0332 advisory.

  - samba: Any Batched (AndX) request processing infinite recursion and heap-based buffer overflow     (CVE-2012-0870)

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

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.
