Remediation
Red Hat statement
Red Hat CloudForms 4.6 and newer versions include the vulnerable component, but there is no risk of exploitation, since there is no possible vector to access the vulnerability. Older Red Hat CloudForms versions do not use the vulnerable component at all. Red Hat Virtualization 4.2 EUS contains the affected version of bootstrap in the packages ovirt-js-dependencies and ovirt-engine-dashboard. These packages are deprecated in Red Hat Virtualization 4.3.
