CVE-2010-2664: Opera before 10.60 allows remote attackers to cause a denial of service (application hang) via certain HTML...

Security readout for executives and security teams

This is an old Opera browser denial-of-service issue. A crafted HTML page could make Opera versions before 10.60 hang. The reported impact is disruption to the browser session, not code execution or data theft. Business urgency is mainly for environments still running legacy Opera builds. Exposure is likely limited to systems that still have Opera versions earlier than 10.60 installed or available for use. Modern managed endpoint fleets are unlikely to be exposed, but legacy kiosks, lab machines, archived images, or unmanaged desktops should be checked. Handle as a low-priority legacy software hygiene item unless old Opera builds are still present in business-critical workflows. The known impact is browser availability, but unsupported software can add operational risk beyond this CVE. Mitigation focus: Inventory endpoints for Opera versions earlier than 10.60.; Upgrade affected Opera installations to 10.60 or later where supported.; Remove unsupported legacy Opera installations where no business need exists..
