The public release of the exploit code increases the possibility of widespread attacks using the Internet Explorer vulnerability. The now public computer code may help cybercriminals craft attacks that use the vulnerability to compromise Windows systems.
As reported on Thursday by McAfee and confirmed by Microsoft, the security vulnerability affects Internet Explorer on all recent versions of Windows. An attacker could gain complete control over a vulnerable system by tricking a user to visit a rigged Web page. New versions of Windows make this exploitation harder, but not impossible.
