          S.A.F.E.R. Security Bulletin 010125.DOS.1.5

    TITLE : Netscape Enterprise Server - REVLOG request problem
    DATE : January 25, 2001
    NATURE : Denial-of-Service
    AFFECTED : Netscape Enterprise Server 3.x with Web Publishing enabled


    Problems exists that allows remote user to crash Netscape Enterprise Server.


    It is possible to crash Netscape Enterprise Server by issuing:

    REVLOG / HTTP/1.0

    Request might be repeated few times in order to crash NES completely.


    Netscape has been contacted on multiple occasions. First time, more than a year ago.

    Although other problems we have reported have been fixed, we have received no response for this issue - to date.

    Workaround is to disable Web Publishing, or disable REVLOG request.
