COMMAND

    netscape

SYSTEMS AFFECTED

    Netscape 4.x (Win 9.x, NT, Linux, Solaris)

PROBLEM

    Jim Paris (not  the one from  Star Trek Voyager)  found following.
    Netscape   4.x   will   crash   when   given   a  content-type  of
    "internal/parser".   Tested versions  are 4.05  and 4.5b1.   Under
    Win95 it simply hangs and needs a three finger salute to kill  it.
    It dies with a bus fault under Linux.  To test it, try

        http://www.jtan.com/~jim/netscape-crash.cgi

    which contains

        #!/bin/sh
        echo Content-type: internal/parser
        echo
        echo If you can see this, your browser is OK!

    It may be possible to do worse than crash a browser.  If this data
    is going to the same place that parsed pages go, one would imagine
    that buffer overflows are present.

SOLUTION

    Earlier versions seem unaffected.  Netscape has been notified.
