The remote NewStart CGSL host, running version MAIN 6.02, has samba packages installed that are affected by multiple vulnerabilities:

  - Multiple heap-based buffer overflows in the NDR parsing in smbd in Samba 3.0.0 through 3.0.25rc3 allow     remote attackers to execute arbitrary code via crafted MS-RPC requests involving (1) DFSEnum     (netdfs_io_dfs_EnumInfo_d), (2) RFNPCNEX (smb_io_notify_option_type_data), (3) LsarAddPrivilegesToAccount     (lsa_io_privilege_set), (4) NetSetFileSecurity (sec_io_acl), or (5) LsarLookupSids/LsarLookupSids2     (lsa_io_trans_names). (CVE-2007-2446)

  - The MS-RPC functionality in smbd in Samba 3.0.0 through 3.0.25rc3 allows remote attackers to execute     arbitrary commands via shell metacharacters involving the (1) SamrChangePassword function, when the     username map script smb.conf option is enabled, and allows remote authenticated users to execute     commands via shell metacharacters involving other MS-RPC functions in the (2) remote printer and (3) file     share management. (CVE-2007-2447)

  - Heap-based buffer overflow in the receive_smb_raw function in util/sock.c in Samba 3.0.0 through 3.0.29     allows remote attackers to execute arbitrary code via a crafted SMB response. (CVE-2008-1105)

  - Samba 3.4 before 3.4.2, 3.3 before 3.3.8, 3.2 before 3.2.15, and 3.0.12 through 3.0.36, as used in the SMB     subsystem in Apple Mac OS X 10.5.8 when Windows File Sharing is enabled, Fedora 11, and other operating     systems, does not properly handle errors in resolving pathnames, which allows remote authenticated users     to bypass intended sharing restrictions, and read, create, or modify files, in certain circumstances     involving user accounts that lack home directories. (CVE-2009-2813)

  - smbd in Samba 3.0 before 3.0.37, 3.2 before 3.2.15, 3.3 before 3.3.8, and 3.4 before 3.4.2 allows remote     authenticated users to cause a denial of service (infinite loop) via an unanticipated oplock break     notification reply packet. (CVE-2009-2906)

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

The remote Redhat Enterprise Linux 4 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2012:0478 advisory.

    Samba is an open-source implementation of the Server Message Block (SMB) or     Common Internet File System (CIFS) protocol, which allows PC-compatible     machines to share files, printers, and other information.

    A flaw in the Samba suite's Perl-based DCE/RPC IDL (PIDL) compiler, used     to generate code to handle RPC calls, resulted in multiple buffer overflows     in Samba. A remote, unauthenticated attacker could send a specially-crafted     RPC request that would cause the Samba daemon (smbd) to crash or, possibly,     execute arbitrary code with the privileges of the root user.
    (CVE-2012-1182)

    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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

The remote MiracleLinux 3 host has packages installed that are affected by a vulnerability as referenced in the AXSA:2012-537:02 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-2012-1182     The RPC code generator in Samba 3.x before 3.4.16, 3.5.x before 3.5.14, and 3.6.x before 3.6.4 does not     implement validation of an array length in a manner consistent with validation of array memory allocation,     which allows remote attackers to execute arbitrary code via a crafted RPC call.

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

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 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2013:0515 advisory.

    The openchange packages provide libraries to access Microsoft Exchange     servers using native protocols. Evolution-MAPI uses these libraries to     integrate the Evolution PIM application with Microsoft Exchange servers.

    A flaw was found in the Samba suite's Perl-based DCE/RPC IDL (PIDL)     compiler. As OpenChange uses code generated by PIDL, this could have     resulted in buffer overflows in the way OpenChange handles RPC calls. With     this update, the code has been generated with an updated version of PIDL to     correct this issue. (CVE-2012-1182)

    The openchange packages have been upgraded to upstream version 1.0, which     provides a number of bug fixes and enhancements over the previous version,     including support for the rebased samba4 packages and several API changes.
    (BZ#767672, BZ#767678)

    This update also fixes the following bugs:

    * When the user tried to modify a meeting with one required attendee and     himself as the organizer, a segmentation fault occurred in the memcpy()     function. Consequently, the evolution-data-server application terminated     unexpectedly with a segmentation fault. This bug has been fixed and     evolution-data-server no longer crashes in the described scenario.
    (BZ#680061)

    * Prior to this update, OpenChange 1.0 was unable to send messages with     a large message body or with extensive attachment. This was caused by minor     issues in OpenChange's exchange.idl definitions. This bug has been fixed     and OpenChange now sends extensive messages without complications.
    (BZ#870405)

    All users of openchange are advised to upgrade to these updated packages,     which fix these issues and add these enhancements.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

It was discovered that Samba, the SMB/CIFS file, print, and login server, contained a flaw in the remote procedure call (RPC) code which allowed remote code execution as the super user from an unauthenticated connection.

Brian Gorenc discovered that Samba incorrectly calculated array bounds when handling remote procedure calls (RPC) over the network. A remote, unauthenticated attacker could exploit this to execute arbitrary code as the root user. (CVE-2012-1182).

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.

A remote code execution flaw in Samba has been fixed :

  - PIDL based autogenerated code uses client supplied size     values which allows attackers to write beyond the     allocated array size. (CVE-2012-1182)

Updated samba4 packages that fix one security issue, multiple bugs, and add various enhancements are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate 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 an open source implementation of the Server Message Block (SMB) or Common Internet File System (CIFS) protocol, which allows PC-compatible machines to share files, printers, and other information.

A flaw was found in the Samba suite's Perl-based DCE/RPC IDL (PIDL) compiler, used to generate code to handle RPC calls. This could result in code generated by the PIDL compiler to not sufficiently protect against buffer overflows. (CVE-2012-1182)

The samba4 packages have been upgraded to upstream version 4.0.0, which provides a number of bug fixes and enhancements over the previous version. In particular, improved interoperability with Active Directory (AD) domains. SSSD now uses the libndr-krb5pac library to parse the Privilege Attribute Certificate (PAC) issued by an AD Key Distribution Center (KDC).

The Cross Realm Kerberos Trust functionality provided by Identity Management, which relies on the capabilities of the samba4 client library, is included as a Technology Preview. This functionality and server libraries, is included as a Technology Preview. This functionality uses the libndr-nbt library to prepare Connection-less Lightweight Directory Access Protocol (CLDAP) messages.

Additionally, various improvements have been made to the Local Security Authority (LSA) and Net Logon services to allow verification of trust from a Windows system. Because the Cross Realm Kerberos Trust functionality is considered a Technology Preview, selected samba4 components are considered to be a Technology Preview. For more information on which Samba packages are considered a Technology Preview, refer to Table 5.1, 'Samba4 Package Support' in the Release Notes, linked to from the References. (BZ#766333, BZ#882188)

This update also fixes the following bug :

* Prior to this update, if the Active Directory (AD) server was rebooted, Winbind sometimes failed to reconnect when requested by 'wbinfo -n' or 'wbinfo -s' commands. Consequently, looking up users using the wbinfo tool failed. This update applies upstream patches to fix this problem and now looking up a Security Identifier (SID) for a username, or a username for a given SID, works as expected after a domain controller is rebooted. (BZ#878564)

All users of samba4 are advised to upgrade to these updated packages, which fix these issues and add these enhancements.

Warning: If you upgrade from Red Hat Enterprise Linux 6.3 to Red Hat Enterprise Linux 6.4 and you have Samba in use, you should make sure that you uninstall the package named 'samba4' to avoid conflicts during the upgrade.
