✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: Applications can reduce exposure by limiting the size of untrusted input passed to regular-expression matching (the overflow requires a subject on the order of 273 MiB) and by avoiding matching untrusted data against highly complex patterns.
