IBM App Connect Enterprise Certified Container may be vulnerable to Denial of Service via CVE-2021-34558. This affects the Operator itself and the ACE server image
DESCRIPTION: Golang Go is vulnerable to a denial of service, caused by the failure to properly assert that the type of public key in an X.509 certificate matches the expected type in the crypto/tls package. By persuading a victim to connect to a specially-crafted TLS server, a remote attacker could exploit this vulnerability to cause a TLS client to panic.
