What is CVE-2018-16875?

The crypto/x509 package in Go versions prior to 1.10.6 and 1.11.x before 1.11.3 allows attackers to exploit chain verification processes. This may lead to excessive CPU usage due to crafted inputs, potentially causing denial of service. Go TLS servers that accept client certificates, as well as TLS clients, are particularly susceptible, making it critical for users to update to secure versions to maintain system integrity.
