CVE-2014-3566

The SSL protocol 3.0, as used in OpenSSL through 1.0.1i and other products, uses nondeterministic CBC padding, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, aka the "POODLE" issue.

Does this matter?

EPSS puts the probability of exploitation in the next 30 days at 100.0%, higher than 100% of all known CVEs. Patch or mitigate before the next change window.
