SSL protocol exchange with the vulnerable device.
Successful repeated exploitation of any of these vulnerabilities may lead to a sustained
Denial-of-Service (DoS); however, vulnerabilities are not known to compromise either the
confidentiality or integrity of the data or the device. These vulnerabilities are not believed to allow
an attacker will not be able to decrypt any previously encrypted information.
