Descriptions

When NGINX Plus or NGINX OSS are configured to use the HTTP/3 QUIC module and the network infrastructure supports a Maximum Transmission Unit (MTU) of 4096 or greater without fragmentation, undisclosed QUIC packets can cause NGINX worker processes to leak previously freed memory.

Cuando NGINX Plus o NGINX OSS están configurados para usar el módulo HTTP/3 QUIC y la infraestructura de red admite una unidad de transmisión máxima (MTU) de 4096 o más sin fragmentación, los paquetes QUIC no revelados pueden hacer que los procesos de trabajo de NGINX pierdan memoria previamente liberada.
