Microsoft has issued a warning concerning a potentially serious vulnerability in all versions of its Internet Explorer Web browser. The bug takes advantage of a weakness that could allow remote code execution and make it possible for hackers to take over unprotected computer systems via corrupted Web pages. The bug revolves around the way that the Internet Explorer manages a computer’s memory when processing Cascading Style Sheets (CSS), a computer language used to describe the presentation semantics of Web pages. By exploiting the computer’s memory management, hackers are able to infiltrate their own code into the stream of instructions being processed by the computer. Thus, they are able to get their code onto the machine and hijack its functions.
As vulnerabilities that allow remote execution of codes are some of the most serious ones out there, Microsoft has provided a sort of ’emergency’ solution for the bug while it continues to work on developing a permanent solution. Microsoft OS and IE users are therefore advices to use its Enhanced Mitigation Experience Toolkit (EMET). EMET will provide users with the ability to deploy security mitigation technologies, to prevent exploitations in arbitrary applications and help to manage risk while users are in the process of transitioning over to latest, more secure updates.
