Description: A vulnerability has been identified in Novell Netware Web Server allowing malicious people to cause a Denial of Service. The problem is that the "CGI2PERL.NLM" module can't handle long strings. This can be exploited by requesting "/perl/a_long_string", by doing this multiple times it is possible to cause a Denial of Service. It has not been proven whether this can be exploited to execute arbitrary code or not. Solution: Novell did issue a patch, but for unknown reasons it is currently not available. If you do not use Perl you may disable it: http://developer.novell.com/ndk/doc/perl5/prl57enu/data/hyyq6w6r.html Provided and/or discovered by: Uffe Nielsen, Protego Original Advisory: http://support.novell.com/cgi-bin/search/searchtid.cgi?/2966549.htm Other References: http://www.kb.cert.org/vuls/id/185593 http://www.protego.dk/advisories/200301.html
