The X.509 certificate-validation functionality in the https implementation in Opera before 12.10 allows remote attackers to trigger a false indication of successful revocation-status checking by causing a failure of a single checking service.

Security readout for executives and security teams

This issue affects old Opera browser versions before 12.10. Opera could incorrectly show that certificate revocation checking succeeded when one checking service failed. That weakens confidence in HTTPS trust decisions, especially for revoked certificates, but the source bundle does not provide severity scoring or evidence of active exploitation. Exposure is most likely on endpoints, legacy images, kiosks, or VDI environments still running Opera before 12.10. Modern supported browsers are not identified as affected in the provided sources. Prioritize remediation where legacy Opera is still used for sensitive browsing or internal portals. If Opera before 12.10 is absent, business urgency is low, but confirm through inventory because the issue affects browser trust decisions. Mitigation focus: Inventory environments for Opera browser versions before 12.10.; Upgrade affected Opera installations to 12.10 or later.; Remove obsolete Opera builds from endpoint images and software catalogs..
