What Changed
Red Hat corrected a Ghostscript vulnerability in the RHEL 9.8 EUS package stream.
What To Validate Now
- Inventory. Locate Ghostscript on RHEL 9.8 EUS deployments, versions, enabled features, exposure paths, owners, and dependent services.
- Establish applicability. Match entitlement, product stream, architecture, source package or image repository, and each advisory's product status. Do not apply one branch's build or digest to another branch.
- Remediate. Use the supported Red Hat channel to deploy ghostscript/libgs 9.54.0-19.el9_8.1. For container images, pin and verify the exact signed digest listed for the matching architecture.
- Validate. Confirm the installed package build, active live patch, or running image digest; restart or redeploy affected workloads where required; validate application and recovery workflows; and record exceptions.
- Retain evidence. Preserve asset and owner identifiers, the applicability decision, before-and-after versions, change approval, installation output, validation results, and any exception or rollback record.
Operational Cautions
Confirm entitlement and branch support, test package or image compatibility, preserve prior packages or image digests and rollback evidence, and do not infer exploitation from severity.
Evidence To Retain
- Exact product, release stream, package or application version, enabled feature, environment, and accountable owner.
- UTC timestamps, authority revision, approved change record, installer or package-manager output, and resulting version.
- Relevant logs and monitoring evidence, test results, exceptions, compensating controls, and rollback decisions.
