CVE-2021-21293: Uncontrolled Resource Consumption

February 2, 2021 (updated October 25, 2022)

Blaze, accepts connections unconditionally on a dedicated thread pool. This has the net effect of amplifying degradation in services that are unable to handle their current request load, since incoming connections are still accepted and added to an unbounded queue.
