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 ...

PYSEC-2026-1426 gRPC connection termination issue

gRPC contains a vulnerability whereby a client can cause a termination of connection between a HTTP2 proxy and a gRPC server: a base64 encoding error for -bin suffixed headers will result in a disconnection by the gRPC server, but is typically allowed by HTTP2 proxies. We recommend upgrading beyo...
