Description Marian Rehak 2021-10-05 10:57:32 UTC 
A remote server can obtain security trust even if the trust is not valid, when multiple CAs have signed the TLS server certificate or in cases
of broken server certificate chains. This indication of trust may be passed along to clients allowing access to unsafe or hijacked services.
