nginx: NGINX: Arbitrary code execution or Denial of Service via heap-based buffer overflow with crafted HTTP/2 headers

A flaw was found in NGINX. When NGINX is configured to proxy HTTP/2 traffic using the ngxhttpproxyv2module or ngxhttpgrpcmodule with specific settings, a remote, unauthenticated attacker can send specially crafted large headers. This can trigger a heap-based buffer overflow, leading to a restart ...
