GHSA-rfhg-rjfp-9q8q: Potential denial of service after connection migration

July 24, 2023

An issue in s2n-quic results in the endpoint shutting down due to a combination of peer-initiated connection migration and duplicate new connection ID frames being received. No AWS services are affected by this issue, and customers of AWS services do not need to take action.

Impacted versions: <=v1.24.0
