Description Robb Gatica 2024-02-14 22:31:50 UTC 
Description:
When NGINX Plus or NGINX OSS are configured to use the HTTP/3 QUIC module, undisclosed requests can cause NGINX worker processes to terminate.

Note: The HTTP/3 QUIC module is not enabled by default and is considered experimental. The issues affect nginx compiled with the ngx_http_v3_module (not compiled by default) if the "quic" option of the "listen" directive is used in a configuration file. For more information, refer to  Support for QUIC and HTTP/3 https://nginx.org/en/docs/quic.html

The issue affects nginx 1.25.0 - 1.25.3.
The issue is fixed in nginx 1.25.4.
