Overview
A remotely exploitable vulnerability has been discovered in Internet Explorer. Exploitation of this vulnerability may lead to the execution of arbitrary code.
Description
| A remotely exploitable buffer overflow vulnerability has been discovered in Internet Explorer versions 5.1, 5.5 and 6.0. The <object> tag contains a "type" field used to determine how Internet Explorer should treat an object. It is possible to bypass the buffer checks on the input to the "type" field by using a specific character and cause a buffer overflow. An attacker could create an HTML file that includes a malicious <OBJECT> tag to execute arbitrary code on the victim's machine. When a victim using a vulnerable version of IE, or other applications that use IE as their HTML interpreter, visits the malicious file (via web page, email message, file sharing, etc.), the attacker-supplied code will be executed. | 
Impact
| Exploitation of this vulnerability may lead to the execution of arbitrary code with the privileges of the current user. | 
Solution
| Microsoft has released MS03-020 to resolve this issue. |
