CVE-2023-24540

A flaw was found in golang, where not all valid JavaScript white-space characters were considered white space. Due to this issue, templates containing white-space characters outside of the character set "\t\n\f\r\u0020\u2028\u2029" in JavaScript contexts that also contain actions may not be properly sanitized during execution.

For Red Hat Enterprise Linux,

• Conmon uses go in unit testing, but not functionally in the package. Go is used only in test files, hence, not in the actual code, thus, conmon is not affected.
• The Go templates in Grafana do not contain any javascript. Thus, it is not affected.
• Ignition does not make use of html/template.

In Red Hat Advanced Cluster Management for Kubernetes (RHACM) the affected containers are behind OpenShift OAuth authentication. This restricts access to the vulnerable golang html/templates to authenticated users only, therefore the impact is low.
