USN-5134-1: Docker vulnerability

9 November 2021

Docker could be made to expose sensitive information over the network.




An information disclosure issue was discovered in the command line interface
of Docker. A misconfigured credential store could result in supplied
credentials being leaked to the public registry, when using the docker login
command with a private registry.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 21.10
Ubuntu 21.04
Ubuntu 20.04
Ubuntu 18.04

In general, a standard system update will make all the necessary changes.
