Patches

• CVE-2020-8558

  The kube-proxy component was found to set the kernel parameter net.ipv4.conf.all.route_localnet=1 in both iptables and ipvs modes to allow local loopback access. An attacker may use the container sharing the host network, or bind and listen to the TCP/UDP service of the local 127.0.0.1 on the cluster node to access the same LAN or adjacent node under the second layer network to obtain interface information. If your service does not set the necessary security certification, it may cause the risk of information leakage.

• CVE-2021-3121

  A program with this vulnerability may crash because of processing some messages that contain malicious Protobuf. If the version of Gogo Protobuf you are using is too low, this vulnerability may exist.

• nokmem

  The node has sufficient disks, but it keeps reporting that the disk is insufficient to create a Pod.
