| summary: Denial of service in chain verification in crypto/x509 |
| description: |- |
| 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. |
