Title: nginx 'ngx_http_process_request_headers()' Remote Buffer Overflow Vulnerability
Severity: CRITICAL
Description:
The 'nginx' program is an HTTP server and mail proxy server.
The application is prone to a remote buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data. The issue occurs in the 'ngx_http_process_request_headers()' function of the 'src/http/ngx_http_request.c' source file when handling certain HTTP requests.
Attackers can exploit this issue to execute arbitrary code within the context of the affected application. Failed exploit attempts will result in a denial-of-service condition.
