✅ 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: 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: Applications can mitigate this issue by avoiding calls to erase_if() on __gnu_pbds::priority_queue containers that use the binary_heap_tag backend. Where predicate-based removal is required, use an alternative container or a different heap backend in application code. Apart from applying a fixed package when one becomes available, no other mitigation is currently available.
