Microsoft warns again on Windows

NEWS
Microsoft issued another slew of warnings about security holes on Wednesday, including a "critical" flaw that affects most Windows PCs. The most serious of the flaws involves DirectX, a library of graphics and multimedia programming instructions used by most PC games, and could allow malicious users to run code of their choice on a vulnerable PC. The flaw is unusually widespread, affecting all versions of DirectX from version 5.2 to the current 9.0a running on all versions of Windows from Windows 98 through the new Windows Server 2003, according to the Microsoft bulletin. The flaw, which received Microsoft's highest severity rating, involves the way DirectX handles MIDI music files. A malformed MIDI file could overrun the buffer in DirectX, at which point extra software embedded in the file would be executed. Exploiting the flaw would entail the creation of a maliciously malformed MIDI file, which vulnerable Windows users would have to be tricked into running, either through email or a Web page. "They'd have to come up with some way to get the user to click on that file," Stephen Toulouse of Microsoft's Security Response Centre said, noting that default security settings in recent versions of Microsoft Outlook email software and the Internet Explorer Web browser prevent the automatic launching of such files. Default security settings are even stronger in Windows Server 2003, Toulouse added, which is why the flaw has a lower rating of "important" for that operating system. Toulouse said there are no known exploits of the flaw, which was discovered by eEye Digital Security, but that affected Windows users should still apply the appropriate patch as soon as possible. Microsoft also announced the availability of a cumulative patch -- rated "important" -- that fixes new and previously reported vulnerabilities in the company's SQL Server software. A third bulletin warned of a "moderate" risk for a new method to launch a denial-of-service attack against a PC that runs the Windows NT 4.0 operating system. The latest alerts continue a busy month of security issues for the software giant. Mike Cherry, an analyst for research firm Directions on Microsoft, said the frequency of security alerts could be bad for Microsoft's image, particularly as they relate to Windows Server 2003, one of the first poster children for the company's "trustworthy computing" initiative. "There should be some concern that, even with the improved testing in that product, they're continuing to find these problems," he said. But no software maker can find every flaw before a product is released, Cherry said, and at least Microsoft is being upfront about potential problems. "They're getting much better about discussing these problems as they're found," he said. "We never would have gotten this kind of information three years ago."

Talkback

Microsoft OS’s are used on PCs and servers throughout the world, and whether accepted or not MS are seen as representatives of America's overwhelming power in the world. Which, unfortunately, makes MS and its OS users a target for any malevolent individual or group with an actual or perceived grudge.

Therefore, it is somewhat incredible that when MS add extra features or applets to its operating systems it also leaves or adds gaping security holes in its products. This makes Microsoft vulnerable to any group that either wants to steal its ideas or compromise its products, while it’s customers are open to all sorts of on-line attacks.

It is obvious that MS should security test its applets and added features, by an independent company if necessary, before releasing them to users.
