Who is Vulnerable?
Apple Safari For Windows 3.1.1 and Prior
Vulnerability Description
A cross application vulnerability has been discovered in Apple Safari on Windows when residing on a system with Microsoft Internet Explorer installed. Safari is a web browsing application developed by Apple. A remote attacker could exploit this issue by convincing a user to open a maliciously crafted HTML, which may allow the attacker to execute arbitrary code on the affected system.
Vulnerability Details
A combination of the default download location in Safari and how the Windows desktop handles executables creates a blended threat in which files may be downloaded to a user's machine without prompting, allowing them to be executed. An attacker could trick users into visiting a specially crafted Web site that could download content to a user's machine and execute the content locally. Successful exploitation of this vulnerability will allow an attacker to take complete control of the affected system.
