Microsoft investigating reports of new IE hole

Microsoft is investigating reports of a serious security flaw in Internet Explorer (IE), but has not yet seen malicious code that exploits the reported flaw, the company said Thursday.

Security experts earlier this week warned that code exploiting a newly discovered security hole in IE is circulating on the Internet. The code exploits a buffer overflow vulnerability in IE 6 and has been confirmed on PCs running Windows XP with Service Pack 1 and Windows 2000, according to Danish Security company Secunia.

The U.S. Computer Emergency Readiness Team (CERT) issued an alert similar to the Secunia advisory. CERT warns that aside from the Web browser, applications such as e-mail clients that rely on browser controls may also be vulnerable. Attackers could gain complete control over a victim's computer by exploiting the flaw, according to Secunia and CERT.

Microsoft is investigating the possible vulnerability, the company said in a statement. However, while Secunia and CERT raise alarm over code exploiting the vulnerability being publicly available, Microsoft said it has not seen that yet. "We have not been made aware of any active exploits of the reported vulnerabilities or customer impact at this time, but we are aggressively investigating the public reports," the company said.

The flaw lies in the way IE handles the SRC and NAME attributes of the "frame" and "iframe" HTML (Hypertext Markup Language) elements, according to the CERT alert. (http://www.kb.cert.org/vuls/id/842160) A user could be attacked via a Web page containing malicious code or an HTML e-mail message.

There is no patch for this flaw, but computers running Windows XP Service Pack 2 appear to be protected, according to Secunia and CERT.

Upon completing its investigation, Microsoft said it will take the appropriate action to protect Windows users. This may include providing a fix through its monthly patch release process or an out-of-cycle security update, the company said.

It really doesn’t get more “gaming laptop” than this.

MSI GS75

As the Maserati or BMW of laptops, it would fit perfectly in the hands of a professional needing firepower under the hood, sophistication and class on the surface, and gaming prowess (sports mode if you will) in between.

This small mobile printer is exactly what I need for invoicing and other jobs such as sending fellow tradesman details or step-by-step instructions that I can easily print off from my phone or the Web.
