A buffer overflow vulnerability exists in the way that Microsoft Internet Explorer processes Cascading Style Sheets (CSS). This may allow an attacker to execute arbitrary code or cause a denial of service.
CSS is a mechanism for adding style to web documents. Microsoft Internet Explorer contains a buffer overflow vulnerability in code that handles CSS. An attacker can exploit this vulnerability by creating a specially crafted style sheet that causes a buffer overflow and heap memory corruption. The buffer overflow can be triggered by viewing an HTML document such as a web page or email message.
An attacker may be able to cause a denial of service or potentially execute arbitrary code with the privileges of the user logged on to the target machine. If the user is logged on with administrative privileges, the attacker could take complete control of a vulnerable system.
