Opera before 10.53 on Windows and Mac OS X does not properly handle a series of document modifications that occur asynchronously, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via JavaScript that writes <marquee> sequences in an infinite loop, leading to attempted use of uninitialized memory. NOTE: this might overlap CVE-2006-6955.

Security readout for executives and security teams

This is an old Opera desktop browser flaw affecting versions before 10.53 on Windows and Mac OS X. A malicious webpage could crash the browser or potentially run code by triggering unsafe document changes through JavaScript. Business urgency is mainly for legacy endpoint cleanup, not modern browser fleets. Exposure is limited to Windows or Mac OS X systems still running Opera versions older than 10.53. Most current environments are unlikely to be exposed unless they retain legacy browsers, lab machines, kiosks, archived gold images, or unmanaged personal software. Treat this as a legacy software hygiene issue. It is serious if vulnerable Opera remains in use, because web content could trigger code execution. For modern fleets without old Opera, priority is low after inventory confirmation. Mitigation focus: Remove or upgrade Opera installations older than 10.53.; Prefer a currently supported browser on all managed endpoints.; Block execution of unsupported legacy browsers where possible..
