Описание
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. For more information, refer to Support for QUIC and HTTP/3 https://nginx.org/en/docs/quic.html .
NOTE: Software versions which have reached End of Technical Support (EoTS) are not evaluated
A flaw was found in the nginx HTTP/3 implementation. This issue may allow an attacker to use a specially crafted QUIC session to trigger a NULL pointer dereference error, causing a worker process to crash, leading to a denial of service.
Отчет
The nginx package as shipped in Red Hat Enterprise Linux 8, 9 and RHSCL is not affected by this vulnerability because support for HTTP3 is not enabled and the vulnerable code was introduced in a newer version of nginx.
