Headline
GHSA-99pg-grm5-qq3v: Docker CLI leaks private registry credentials to registry-1.docker.io
Impact
A bug was found in the Docker CLI where running docker login my-private-registry.example.com with a misconfigured configuration file (typically ~/.docker/config.json) listing a credsStore or credHelpers that could not be executed would result in any provided credentials being sent to registry-1.docker.io rather than the intended private registry.
Patches
This bug has been fixed in Docker CLI 20.10.9. Users should update to this version as soon as possible.
Workarounds
Ensure that any configured credsStore or credHelpers entries in the configuration file reference an installed credential helper that is executable and on the PATH.

Dell Unity, Dell UnityVSA, and Dell Unity XT versions prior to 5.2.0.0.5.173 contain a plain-text password storage vulnerability when certain off-array tools are run on the system. The credentials of a user with high privileges are stored in plain text. A local malicious user with high privileges may use the exposed password to gain access with the privileges of the compromised user.
Docker CLI is the command line interface for the docker container runtime. A bug was found in the Docker CLI where running `docker login my-private-registry.example.com` with a misconfigured configuration file (typically `~/.docker/config.json`) listing a `credsStore` or `credHelpers` that could not be executed would result in any provided credentials being sent to `registry-1.docker.io` rather than the intended private registry. This bug has been fixed in Docker CLI 20.10.9. Users should update to this version as soon as possible. For users unable to update ensure that any configured credsStore or credHelpers entries in the configuration file reference an installed credential helper that is executable and on the PATH.
