Subject Name:            Samba
Subject Summary:         SMB/CIFS Server
Subject Home:            http://www.samba.org/
Subject Versions:        * >= 2.2.2 && * <= 2.2.6

Vulnerability Id:        debian:DSA-200
Vulnerability Scope:     global (not OpenPKG specific)

Attack Feasibility:      run-time
Attack Vector:           remote network
Attack Impact:           privilege escalation, arbitrary code execution

Description:
    A vulnerability in Samba [0] versions 2.2.2 through 2.2.6 was
    discovered by the Debian Samba maintainers [1]. A bug in the
    length checking for encrypted password change requests from clients
    could be exploited using a buffer overrun attack on the smbd(8)
    stack. This attack would have to be crafted in such a way that
    converting a DOS codepage string to little endian UCS2 unicode
    would translate into an executable block of code.
    
    Check whether you are affected by running "<prefix>/bin/rpm -q
    samba". If you have an affected version of the samba package (see
    above), please upgrade it according to the solution below.
