✅ Remediation

The RHEL-8 based Middleware Containers container images provided by this update can be downloaded from the Red Hat Container Registry at registry.access.redhat.com. Installation instructions for your platform are available at Red Hat Container Catalog (see References). Dockerfiles and scripts should be amended either to refer to this new image specifically, or to the latest image generally. Workaround: Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability. Applying the upstream patch or vendor-supplied security update is the recommended resolution. 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: To mitigate this issue, disable GSSAPI key exchange in the OpenSSH server configuration. This prevents the server from processing GSSAPI messages, eliminating the vulnerability's attack surface. Edit `/etc/ssh/sshd_config` and add or modify the line: ``` GSSAPIKeyExchange no ``` After saving the changes, restart the `sshd` service for the mitigation to take effect. This action will prevent users from authenticating via GSSAPI. ``` # systemctl restart sshd ``` 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: To mitigate this issue, avoid processing untrusted ISO9660 images with applications that utilize `libarchive`. Users should only extract or read content from ISO images obtained from trusted sources.
