"Several issues have been identified in Samba, the SMB/CIFS file- and
print-server implementation for GNU/Linux.

  - CVE-2007-2444
    When translating SIDs to/from names using Samba local
    list of user and group accounts, a logic error in the
    smbd daemon's internal security stack may result in a
    transition to the root user id rather than the non-root
    user. The user is then able to temporarily issue
    SMB/CIFS protocol operations as the root user. This
    window of opportunity may allow the attacker to
    establish addition means of gaining root access to the
    server.

  - CVE-2007-2446
    Various bugs in Samba's NDR parsing can allow a user to
    send specially crafted MS-RPC requests that will
    overwrite the heap space with user defined data.

  - CVE-2007-2447
    Unescaped user input parameters are passed as arguments
    to /bin/sh allowing for remote command execution."
