Описание
When NGINX Plus or NGINX OSS are configured to use the HTTP/3 QUIC module, undisclosed HTTP/3 encoder instructions can cause NGINX worker processes to terminate or cause or other potential impact.
A flaw was found in the nginx HTTP/3 implementation. Undisclosed HTTP/3 encoder instructions can trigger an out-of-bounds write error, causing worker processes to crash, leading to a denial of service or other potential impacts.
Отчет
As this flaw allows a remote attacker to cause a denial of service, it has been rated with an important severity. The nginx package as shipped in Red Hat Enterprise Linux 8, 9 and RHSCL is not affected by this vulnerability because the support for HTTP/3 is not enabled and the vulnerable code was introduced in a later version of nginx.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
