✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability. Workaround: Upgrade to js-yaml 5.2.0 or later. Where an immediate upgrade is not possible, avoid parsing untrusted YAML documents that use merge keys ('<<'), or apply size and time limits when parsing untrusted YAML input. Workaround: Avoid using the YAML11_SCHEMA when parsing untrusted YAML input, or upgrade to js-yaml 5.2.1 or later. Applications using the default schema (CORE_SCHEMA) are not affected.
