Buffer Overflow in Netware Web Server PERL Handler
The Netware Enterprise Server does not perform proper bounds check on
requests passed to the PERL interpreter through the PERL virtual
directory. This results in a buffer overflow condition, when large
requests are sent to the PERL interpreter.
* Netware 5.1 SP6
* Netware 6
The issue can be triggered by requesting the PERL virtual directory
followed by a long string.
http://server/perl/aaaaaa...[Unspecified number of characters]
The vulnerability occurs in the CGI2PERL.NLM module.
A request as shown above will overrun the allocated buffer and overwrite
EIP, causing the server to ABEND and either suspend the process or restart
itself, thereby creating a Denial of Service situation.
