Summary
Denial of service in chain verification in crypto/x509
Details

The crypto/x509 package 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 verifying certificates are affected.
