Red Hat Source-to-Image 1.6.4 Addresses Seven Flaws
Quick Answer
RHSA-2026:69917 updates OpenShift Source To Image to version 1.6.4 for seven dependency vulnerabilities. Update the S2I tooling used by builds; an application image created before that change is a separate artifact and is not retroactively altered.
Confirm Scope And Apply The Supported Fix
What to do now: Locate S2I binaries and build environments, deploy the supported 1.6.4 artifacts, and confirm build jobs use the updated tooling rather than an older pinned image or executable.
Source check: 2026-10-02 UTC. This notice reflects the primary-source evidence described below, not a completed update or exploitation test. Recheck the advisory and supported distribution channel before changing production.
Scope And Authority
| Product scope | Red Hat OpenShift Source-to-Image 1.6 |
|---|---|
| Advisory | RHSA-2026:69917 |
| CVEs | CVE-2026-15789, CVE-2026-33818, CVE-2026-41178, CVE-2026-56853, CVE-2026-56860, CVE-2026-56862, CVE-2026-75593 |
| Authoritative release date | RHSA-2026:69917: 2026-09-22T08:24:04+00:00 (CSAF initial release) |
| Authority revision date | RHSA-2026:69917: 2026-09-22T08:24:05+00:00 (CSAF revision history). CSAF generation timestamps are not advisory revision dates. |
| Affected versions | The exact entitled Red Hat OpenShift Source-to-Image 1.6 builds before the branch-specific package, image, or digest listed by Red Hat. |
| Fixed version | Red Hat OpenShift Source-to-Image 1.6.4 advisory-listed builds |
| CVSS base score | 6.5 / 7.5 (CVSS v3.1) |
| CVSS severity | Medium to High |
| Exploitation status | RHSA-2026:69917 does not state that these flaws are being exploited. That is not confirmation that exploitation has not occurred. |
What Changed
The advisory includes BuildKit file-escape issues affecting file integrity and resource-exhaustion flaws in Go parsing/networking and telemetry dependencies. Their affected components and prerequisites differ; the advisory is not a claim that every resulting application image exposes all seven vulnerabilities.
What To Validate Now
- Inventory. Locate Red Hat OpenShift Source-to-Image 1.6 deployments, versions, enabled features, exposure paths, owners, and dependent services.
- Establish applicability. Compare each deployment with the authority's affected-version statement: The exact entitled Red Hat OpenShift Source-to-Image 1.6 builds before the branch-specific package, image, or digest listed by Red Hat. Do not infer applicability from product family or severity alone.
- Remediate. Upgrade existing S2I installations to 1.6.4 through the supported channel and update pinned build environments as required. Restrict BuildKit control access to trusted users/services while arranging the change.
- Validate. Record the S2I build/version actually invoked, run a representative approved source-to-image build and verify its output and registry publication. Assess any rebuild/redeployment of application outputs separately.
- 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
Use the exact supported release stream and repository. Test dependencies, clusters, integrations, and rollback before broad deployment; a CVSS rating or reachable feature is not evidence of exploitation.
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.
