      Lotus Notes/Domino R6-beta PROTOS LDAP Denial of Service Regression


    In July 2001, the PROTOS protocol-testing group at the University of Oulu
    in Finland released an LDAP protocol test suite that exposed flaws in LDAP
    implementations from multiple vendors. [1]

    Lotus Domino R5.0.7 and earlier were affected by the PROTOS LDAP issues,
    resulting in buffer overflows and denial of service against the Domino
    server. Lotus addressed these issues in Domino R5.0.7a, released May 18
    2001. [2]

    While regression testing the pre-release and beta versions of Lotus Domino
    R6 with the PROTOS LDAP test suite, we found that these releases were
    vulnerable to the issues PROTOS discovered.


    Vulnerable systems:
     * Lotus Notes/Domino R6 pre-release and beta versions
     * Lotus Domino R5.0.7 and earlier

    Immune systems:
     * Lotus Notes/Domino R6.0 Gold
     * Lotus Notes/Domino R6.0.1
     * Lotus Notes/Domino R5.0.7a through R5.0.12

    Credit for discovery of this vulnerability goes to the PROTOS project.
    Please see their LDAP test suite page for more information. [1]

    Vendor status and information:
    Lotus was notified and they have fixed this vulnerability. Lotus
    originally tracked these issues as SPR #DWUU4W6NC8 and are tracking the R6
    beta issues with this SPR. [3] See the References section for more

    Users running R6 beta and pre-release builds should upgrade to R6.0 Gold
    or higher. Due to other vulnerabilities discovered in R6.0 Gold, you
    should consider upgrading to R6.0.1, which was released in February 2003.

    Users running R5.0.7a and higher are not affected.
