Opera DHTML background property denial of service
|opera-dhtml-background-dos (27977)||Medium Risk|
Opera is vulnerable to a denial of service, caused by a memory corruption issue that can occur when the "background" property of a DHTML element is set to an overly long HTTP or HTTPS URL. A remote attacker could exploit this vulnerability to cause a victim's browser to crash, if the attacker could persuade the victim to visit a malicious Web page.
