nginx HTTP Request Header Remote Buffer Overflow
High Nessus Network Monitor Plugin ID 5216
SynopsisThe remote web server is affected by a remote denial of service vulnerability.
DescriptionThe remote host is running a version of nginx web server earlier than 0.5.38, 0.6.39, or 0.7.62. Such versions are potentially affected by a remote denial of service vulnerability because the application fails to to perform adequate bounds checking in the 'ngx_http_process_request_headers()' function of the 'src/http/ngx_http_request.c' source file. An attacker, exploiting this flaw, can cause the web server to crash, or potentially run arbitrary code subject to the privileges of the web server process.
SolutionApply the patch from the vendor, or upgrade to nginx 0.5.38, 0.6.39, or 0.7.62
