Multiple Vulnerabilities in Mozilla Firefox Could Allow for Arbitrary Code Execution

Read Time:39 Second

Multiple vulnerabilities have been discovered in Mozilla Firefox and Firefox Extended Support Release (ESR), the most severe of which could allow for arbitrary code execution.

Mozilla Firefox is a web browser used to access the Internet.
Mozilla Firefox ESR is a version of the web browser intended to be deployed in large organizations.
Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution in the context of the logged on user. Depending on the privileges associated with the user an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.

Update description:

This package release removes references completely for Dockershim. If you still require support for Docker please visit for more info https://www.mirantis.com/blog/mirantis-to-take-over-support-of-kubernetes-dockershim-2/

This was originally a bug-fix that removed arguments no longer used in the 1.24 Kublet which stemmed from Dockershim. Since Dockershim is now out of tree this package won’t support it unless there’s a compelling use-case.
