Subject Name:            Samba
Subject Summary:         SMB/CIFS Server
Subject Home:            http://www.samba.org/
Subject Versions:        * <= 3.0.6

Vulnerability Id:        CVE-2004-0807, CVE-2004-0808
Vulnerability Scope:     global (not OpenPKG specific)

Attack Feasibility:      run-time
Attack Vector:           remote network
Attack Impact:           denial of service

Description:
    According to a security advisory [1] from the Samba team and two
    corresponding security advisories [2][3] from iDEFENSE, two Denial of
    Service (DoS) vulnerabilities exists in the Samba SMB/CIFS server [0].
    The first DoS bug is in smbd(8) and may allow an unauthenticated user
    to cause smbd(8) to spawn new processes, each one entering an infinite
    loop. After sending a sufficient amount of packets it is possible to
    exhaust the memory resources on the server. The second DoS bug in
    nmbd(8) may allow an attacker to remotely crash the nmbd(8) daemon.
