## Technical details

A buffer overflow vulnerability exists in NCSA WebServer (NCSA httpd) version 1.5c. The flaw is located in the handling of incoming network requests, where insufficient bounds checking allows an attacker to overwrite memory. A remote, unauthenticated attacker can exploit this by sending a specially crafted request to the server. Successful exploitation results in arbitrary code execution with the privileges of the web server process, leading to full system compromise.
