A Denial of Service vulnerability was found in .NET Core project templates that utilize JWT-based authentication tokens. This issue may allow an unauthenticated client to consume arbitrarily large amounts of server memory, potentially triggering an out-of-memory condition on the server and making the server no longer able to respond to legitimate requests.

Mitigation

Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
