Overview
Affected versions of this package are vulnerable to Infinite loop via the nghttp2 process. An attacker can exhaust CPU resources by sending specially crafted DNS over HTTPS exchanges that trigger an unbounded I/O read loop. This is only exploitable if the system is configured to use the nghttp2 library to process incoming DNS over HTTPS queries.
