Description: The issue allows remote attackers to cause a denial of service, consuming memory and CPU, via a crafted certificate in the TLS certificate handshake message. This is due to a buffer overflow in the asn1 signature function, which does not check the result of get asn1 length() for minimum or maximum size.
