CVE-2010-4049
Opera before 10.63 allows remote attackers to cause a denial of service (application crash) via a Flash movie with a transparent Window Mode (aka wmode) property, which is not properly handled during navigation away from the containing HTML document.
Does this matter?
Lower severity and a low EPSS score (1.85%). Track it; it rarely justifies an emergency change on its own.
