What Changed

Red Hat released RHSA-2026:96206 for RHEL 6 Extended Lifecycle Support Extension, addressing a buffer overflow while processing a crafted GIF file. The update provides the distribution packages listed below; keep the Red Hat release and support channel matched during remediation.

What To Validate Now

  1. Inventory. Record GD libraries, image upload paths and applications loading libgd.
  2. Establish applicability. RHEL 6 Extended Lifecycle Support Extension: installations of the GD packages requiring RHSA-2026:96206. Match the full installed RPM, architecture and repository to the vendor product tree; a universal upstream version range is not stated.
  3. Remediate. Apply RHSA-2026:96206 through the entitled Red Hat repositories. The fixed source build is gd-0:2.0.35-11.el6_10.1. Install the matching binary packages for the supported stream and architecture.
  4. Validate. Restart consumers of the updated library, test trusted GIF processing and confirm complete RPM versions.
  5. 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

Red Hat identifies no practical temporary mitigation. Isolate untrusted image processing while arranging the entitled update; this ELS Extension package is not a general RHEL 6 lifecycle extension.

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.
