✅ 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: Applications that process Cryptographic Message Syntax (CMS) EnvelopedData messages should be configured to only accept input from trusted sources. Restricting network access to services that process untrusted CMS data can also reduce exposure to this Denial of Service vulnerability. 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.
