JSON

The crypto/x509 package of Go before 1.10.6 and 1.11.x before 1.11.3 does
not limit the amount of work performed for each chain verification, which
might allow attackers to craft pathological inputs leading to a CPU denial
of service. Go TLS servers accepting client certificates and TLS clients
are affected.
