✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: To mitigate this vulnerability, do not compile regular expressions from untrusted sources. Standard safeguards such as Regexp.timeout or limiting the length of the input pattern do not protect against this issue.
