✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 Workaround: To mitigate this limit the length of incoming package specifiers (spec.rawSpec) before they reach the resolution service. Enforce hard CPU time limits or timeouts on isolated build jobs and package resolution processes. 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.
