| Doc Text: |
A flaw was found in the Go standard library packages `crypto/x509` and `crypto/tls`. During the process of building a certificate chain, an attacker can provide a large number of intermediate certificates. This excessive input is not properly limited, leading to an uncontrolled amount of work being performed. This can result in a denial of service (DoS) condition, making the affected system or application unavailable to legitimate users.
