Security Advisory Recommended Actions
If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by upgrading to a version listed
in the Fixes introduced in column. If the table lists only an older version
than what you are currently running, or does not list a non-vulnerable version,
then no upgrade candidate currently exists.
Mitigation
To avoid this vulnerability, F5 recommends that you perform tcpdump during
troubleshooting sessions and avoid running it unattended for a long duration of
time.

CVE-2021-1067
NVIDIA SHIELD TV, all versions prior to 8.2.2, contains a vulnerability in the implementation of the RPMB command status, in which an attacker can write to the Write Protect Configuration Block, which may lead to denial of service or escalation of privileges.
CVE-2021-1068
NVIDIA SHIELD TV, all versions prior to 8.2.2, contains a vulnerability in the NVDEC component, in which an attacker can read from or write to a memory location that is outside the intended boundary of the buffer, which may lead to denial of service or escalation of privileges.
CVE-2021-1069
NVIDIA SHIELD TV, all versions prior to 8.2.2, contains a vulnerability in the NVHost function, which may lead to abnormal reboot due to a null pointer reference, causing data loss.

CVE-2020-26252
OpenMage is a community-driven alternative to Magento CE. In OpenMage before versions 19.4.10 and 20.0.6, there is a vulnerability which enables remote code execution.
In affected versions an administrator with permission to update product data to be able to store an executable file on the server and load it via layout xml.
The latest OpenMage Versions up from 19.4.10 and 20.0.6 have this issue solved.
CVE-2020-26278
Weave Net is open source software which creates a virtual network that connects Docker containers across multiple hosts and enables their automatic discovery. Weave Net before version 2.8.0 has a vulnerability in which can allow an attacker to take over any host in the cluster.
Weave Net is supplied with a manifest that runs pods on every node in a Kubernetes cluster, which are responsible for managing network connections for all other pods in the cluster. This requires a lot of power over the host, and the manifest sets `privileged: true`, which gives it that power.
It also set `hostPID: true`, which gave it the ability to access all other processes on the host, and write anywhere in the root filesystem of the host. This setting was not necessary, and is being removed.
You are only vulnerable if you have an additional vulnerability (e.g. a bug in Kubernetes) or misconfiguration that allows an attacker to run code inside the Weave Net pod,
No such bug is known at the time of release, and there are no known instances of this being exploited.
Weave Net 2.8.0 removes the hostPID setting and moves CNI plugin install to an init container.
Users who do not update to 2.8.0 can edit the hostPID line in their existing DaemonSet manifest to say false instead of true,
arrange some other way to install CNI plugins (e.g. Ansible) and remove those mounts from the DaemonSet manifest.
