JSON

A flaw was found in the nginx HTTP/3 implementation. If the network infrastructure supports a Maximum Transmission Unit (MTU) of 4096 or greater without fragmentation, undisclosed QUIC packets can trigger a use-after-free condition, causing worker processes to leak previously freed memory.

Mitigation

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.
