✅ 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 issue, applications utilizing libsoup that process HTTP responses should be configured to only communicate with trusted endpoints. Implement network egress filtering to restrict vulnerable applications from connecting to untrusted external services, thereby reducing the exposure to specially crafted multipart HTTP responses.
