14.1 - v1.15.12-lts.1

This is the first fixed release by KLTS for v1.15.12.

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-2020-8559
This is a security vulnerability of the kube-apiserver component. An attacker can intercept certain upgrade requests sent to the node kubelet, and forward the request to other target nodes through the original access credentials in the request that could allow an attacker to escalate privileges from a node compromise to a full cluster compromise.
