CVE-2020-25645: Fixed an issue which traffic between two Geneve

 for the specific UDP port used by the GENEVE tunnel allowing anyone
 between the two endpoints to read the traffic unencrypted (bsc#1177513).

CVE-2020-0429: Fixed a memory corruption due to a use after free which
 could have led to local privilege escalation (bsc#1176931).

 mishandled invalid descriptors (bsc#1173942).
