Description

A flaw was found in Go's `crypto/x509` package. A remote attacker could exploit this by presenting a specially crafted certificate chain containing a large number of policy mappings. This inefficient validation process consumes excessive resources, which can lead to a denial of service (DoS) for applications or systems performing certificate validation.
