The following security issues were fixed: - CVE-2020-25645: Fixed an issue which traffic between two Geneve endpoints may be unencrypted when IPsec is configured to encrypt traffic 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 to local privilege escalation (bsc#1176931). - CVE-2020-11668: Fixed an issue where the Xirlink camera USB driver mishandled invalid descriptors (bsc#1173942). - CVE-2020-1749: Use ip6_dst_lookup_flow instead of ip6_dst_lookup (bsc#1165631).

When an encrypted tunnel is created between two hosts, the kernel isn't correctly routing tunneled data over the encrypted link; rather sending the data unencrypted. This would allow anyone in between the two endpoints to read the traffic unencrypted. The main threat from this vulnerability is to data confidentiality.
