Phusion Webserver is a commercial HTTP server that runs on Microsoft Windows 9x/NT/2000 operating systems.

It is possible for a remote attacker to deny service to legitimate users of the service by submitting an excessively long web request (approximately 3000+ bytes).

It should be noted that this issue is due to a remotely exploitable buffer overflow condition.

Phusion Webserver is a commercial HTTP server that runs on Microsoft Windows 9x/NT/2000 operating systems.

Phusion Webserver does not perform sufficient bounds checking of externally supplied data. As a result, it is possible for a remote attacker to submit an excessively long web request which may cause stack variables to be overwritten with attacker-supplied instructions.

As webservers normally run with SYSTEM privileges on Microsoft Windows operating systems, this may result in a full compromise of a host running the vulnerable software.

It should be noted that this unchecked buffer may also be exploited to cause a denial of service condition.
