Publisher Name: OpenPKG GmbH Publisher Home: http://openpkg.com/ Advisory Id (public): OpenPKG-SA-2007.012 Advisory Type: OpenPKG Security Advisory (SA) Advisory Directory: http://openpkg.com/go/OpenPKG-SA Advisory Document: http://openpkg.com/go/OpenPKG-SA-2007.012 Advisory Published: 2007-05-17 19:46 UTC Issue Id (internal): OpenPKG-SI-20070517.01 Issue First Created: 2007-05-17 Issue Last Modified: 2007-05-17 Issue Revision: 04 ____________________________________________________________________________ Subject Name: Samba Subject Summary: CIFS/SMB Server Subject Home: http://www.samba.org/ Subject Versions: 3..* <= 3.0.24 Vulnerability Id: CVE-2007-2444, CVE-2007-2446, CVE-2007-2447, CVE-2007-2453, CVE-2007-2454 Vulnerability Scope: global (not OpenPKG specific) Attack Feasibility: run-time Attack Vector: remote network Attack Impact: denial of service, privilege escalation, arbitrary code execution

Description:

    Multiple vulnerabilities were found in the CIFS/SMB server     implementation Samba [0]:     

  1. A logic error in the SID/Name translation functionality in smbd(8) allows local users to gain temporary privileges and execute SMB/CIFS protocol operations via unspecified vectors that cause the daemon to transition to the "root" user (CVE-2007-2444) [1].
  2. Multiple heap-based buffer overflows in the NDR parsing in smbd(8) allow remote attackers to execute arbitrary code via crafted MS-RPC requests (CVE-2007-2446) [2].
  3. The MS-RPC functionality in smbd(8) 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) [3].
  4. A buffer overflow in the "nss_winbind" library, as used in the winbindd(8) daemon, allows attackers to execute arbitrary code via the gethostbyname(3) and getipnodebyname(3) functions (CVE-2007-0453) [4].
  5. A format string vulnerability in the "afsacl" VFS module in allows context-dependent attackers to execute arbitrary code via format string specifiers in a filename on an AFS file system, which is not properly handled during Windows ACL mapping (CVE-2007-0454)
    [5].
