    Synopsis
    ========

    Samba contains a bug that could lead to remote execution of arbitrary
    code.

    Background
    ==========

    Samba is a freely available SMB/CIFS implementation which allows
    seamless interoperability of file and print services to other SMB/CIFS
    clients.

    Affected packages
    =================

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 net-fs/samba <= 3.0.9 >= 3.0.9-r1

    Description
    ===========

    Samba contains a bug when unmarshalling specific MS-RPC requests from
    clients.

    Impact
    ======

    A remote attacker may be able to execute arbitrary code with the
    permissions of the user running Samba, which could be the root user.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All samba users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=net-fs/samba-3.0.9-r1"
