Just one day after&#160;Microsoft issued a massive set of security patches for its software, hackers have begun posting code showing how to exploit one of the flaws.The proof-of-concept code, posted Wednesday to the Milw0rm Web site, exploits a bug in the Microsoft Works file converter software that is part of Office 2003 and can be used to run unauthorized software on a victim&#39;s computer.The flaw also affects Works 8 and Works Suite 2005. To fall prey to the attack, a victim would first have to open a malicious Works attachment.Hackers have uncovered many of these file-format bugs in recent years, and they are generally not used in widespread attacks. In fact, security vendor Symantec predicts that we&#39;ll see fewer of these attacks in the months ahead as online criminals increasingly rely on browser bugs to do their dirty work.&quot;The bad guys, they&#39;re looking for different ways to trick people,&quot; said Wayne Periman, director of development with Symantec Security Response. &quot;The popular method of choice is to exploit plugins in browsers right now.&quot;Still, Periman expects criminals to try out this latest attack code. &quot;It&#39;s so simple,&quot; he said. &quot;All you have to do is get someone to open the document.&quot;As of Wednesday, Symantec had not seen any signs of attackers taking advantage of any of the flaws that Microsoft fixed this week.The software vendor released 11 sets of patches this week, fixing 17 flaws in its products, but this is the first exploit code to pop up following Tuesday&#39;s updates. A second program exploiting one of these vulnerabilities -- this one in an ActiveX control used by the Visual FoxPro database -- was posted to Milw0rm in September, months before Microsoft patched the issue.

(InfoWorld) - Users are being advised to disable a certain type of file in Microsoft's Windows Media Player software following the discovery of a new security hole in the software. The flaw, which affects Windows Media Player versions 9 and 10, could allow a malicious hacker to run unauthorized software on a victim's PC or cause a denial of service attack, according to security company FrSIRT, which rated the problem critical in an advisory Thursday. The flaw is due to a buffer overflow error that can occur when Windows Media Player is used to run ".asx" media files, according to a warning from eEye Digital Security . Such files open automatically in a Web browser, meaning a hacker would need only to post an infected .asx file in a Web page and then try to lure users to visit the page, eEye Digital said. An infected file could also be sent via email, in which case users would need to be persuaded to open it. Microsoft said an initial investigation revealed that the "proof of concept" code could allow an attacker to execute code on a user's machine. It said it was unaware of any attempts to exploit the vulnerability, and it was unclear Friday morning if the proof of concept code it referred to was in the hands of hackers. Users can protect against the vulnerability in Internet Explorer by preventing it from opening .asx files automatically. Turning off Active Scripting would also greatly reduce, but not eliminate, the risk, Microsoft said. FrSIRT also recommended that users upgrade to Windows Media Player 11 , which it said is not affected. Microsoft was still determining Friday whether it needed to issue an "out of cycle" security fix for the problem or patch it with its next monthly software update. The flaw was originally reported on Nov. 22, when it was identified only as a denial-of-service issue. Some discussion boards described the problem as a "zero-day exploit," although it was unclear if that was the case. Zero-day exploits occur when exploit code is released on the same day that a flaw is uncovered, giving users no time to protect themselves. It's been another busy week for Microsoft's security teams. On TuesdayÂ the company warnedÂ of an unpatched vulnerability in Word that had been the subject of what it called "limited attacks." And on Thursday it said it was readying several patches for Visual Studio and Windows that it plans to release next week. The patches currently due for next weekÂ do not address the problemsÂ with Word and Windows Media Player.
