Description
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.
Statement
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.
