Opera before 11.10 does not properly handle hidden animated GIF images, which allows remote attackers to cause a denial of service (CPU consumption) via an image file that triggers continual repaints.

Security readout for executives and security teams

This is an old Opera browser denial-of-service issue. A web page or image could make affected Opera versions before 11.10 consume CPU by repeatedly repainting a hidden animated GIF. The supported impact is browser or endpoint performance disruption, not data theft or code execution. Exposure is most likely limited to legacy environments still running Opera versions earlier than 11.10, including unmanaged endpoints, old virtual desktops, kiosks, or archived portable browser installs. Treat as a low-priority legacy hygiene issue unless old Opera is still deployed in business workflows. The main business risk is avoidable endpoint disruption from unsupported browser software. Mitigation focus: Upgrade Opera installations older than 11.10 to a fixed or supported version.; Check Opera changelogs and vendor guidance for platform-specific remediation details.; Remove unsupported legacy Opera builds from managed endpoints..
