(InfoWorld) - Microsoft has released its monthly set of security patches , fixing problems in Windows, Internet Explorer and in the SSL (Secure Sockets Layer) software used for secure Web browsing. In total, Microsoft released six sets of patches, called updates, fixing 15 flaws in its products. Four of these updates are rated critical and administrators should patch them as soon as possible, security experts said Tuesday. Many of the flaws that Microsoft patched on Tuesday can be exploited via the Web. In particular the MS07-033 update, which fixes bugs in Internet Explorer and MS07-031 , which addresses a critical flaw in the SSL libraries used by Windows. The SSL flaw is particularly interesting because it affects users who are visiting supposedly trustworthy Web sites, and because it could also affect non-Microsoft browsers like Firefox and Opera, said Amol Sarwate, manager of Qualys, Inc.'s vulnerability research lab. "It will affect all the browsers that call the libraries that are in the Windows operating system," he said. Although Microsoft warned that this flaw could be used by attackers to run unauthorized software on the victim's computer, this would be hard to do. "Attempts to exploit this vulnerability would most likely result in the Internet Web browser or application exiting," Microsoft wrote in its MS07-031 bulletin. "The system would not be able to connect to Web sites or resources using SSL ... until a restart of the system." The two other critical updates are MS07-035 , which fixes a bug in the core Windows operating system's Win32 API (application programming interface), and MS07-034 , which fixes bugs in Outlook Express and Windows Mail. Because MS07-035 could be exploited via the Web, it should also be patched as soon as possible, Sarwate said. The other updates released Tuesday fix less-critical flaws in Windows Vista and Microsoft's Visio drawing software. The Vista update is noteworthy because it marks the first time that Microsoft has patched a flaw that was introduced in the Vista operating system, Sarwate said. Previous Vista patches have repaired "legacy" code that was written for earlier versions of Windows, and then reused in Vista. But the MS07-032 update applies to Vista only. This flaw, rated "moderate" by Microsoft, could allow an attacker to gain unauthorized access to information such as administrative passwords stored within Windows.

(InfoWorld) - MicrosoftÂ released its February set of security updates Tuesday, including critical fixes for bugs in Office and the scanning engine used by the company's security products. The security software flaw is of particular concern because it could, in theory, be very easily exploited by an attacker to run unauthorized software on a victim's PC. The bug has to do with the way that Microsoft's Malware Protection Engine, used by Windows Live One Care and Windows Defender, processes PDF files. Windows Defender is available for free and ships with Microsoft's Vista operating system. "An attacker could exploit the vulnerability by constructing a specially crafted PDF that could potentially allow remote code execution when the target computer system receives, and the Microsoft Malware Protection Engine scans, the PDF file," Microsoft said in its bulletin on the patch. This engine is also used by Microsoft's Antigen and Windows Forefront Security products, meaning that Exchange servers running these products could also be compromised. Although there is not yet any known attack that exploits this flaw, it could become a serious problem for Windows users running Microsoft's security products, according to Amol Sarwate, vulnerability lab manager at Qualys. "These attacks are very difficult to avoid," he said. "These products run automatically in the background." Symantec rated this scanning engine flaw the most critical of the vulnerabilities patched on Tuesday. In total, six of Microsoft's 12 updates are rated as "critical," while the other six have the less-serious rating of "important." Among the patches is a widely anticipated update for Microsoft WordÂ that fixes six bugs in Microsoft's word processing software. Hackers had been exploiting a number of these bugs in very targeted attacks over the past few months. Other critical patches fix bugs in the ActiveX HTML Help control and Microsoft Data Access Components, both used by Windows, as well as flaws in Office and Internet Explorer.

(InfoWorld) - Microsoft Corp. has rolled out its monthly security updates for December, patching critical flaws in Internet Explorer, Windows Media Format, and the Visual Studio 2005 development software. The seven security patches address 11 bugs, including two in the Windows Media Player software. However, no fixes were provided for two Microsoft Word flaws that have been used in a small number of attacks during the past week. Microsoft had said it would release only six patches on Tuesday, but the company added the Windows Media Format update at the last minute, after reports of attacks based on this vulnerability began surfacing. The Windows Media Format is used by Microsoft's Windows Media Player software. In late November, security vendors warned that a buffer overflow error could occur when the Windows Media Player processed ".asx" (Advanced Stream Redirector) media files, meaning that users would first need to be tricked into opening a malicious media file for the attack to work. In its update Tuesday, Microsoft also patched a similar bug in the way the media player processes ".asf" (Advanced Systems Format) files. The Internet Explorer patch fixes four bugs. It is also rated critical, and is noteworthy because some of these bugs will probably begin to be exploited by hackers by week's end, said Gunter Ollmann, director of IBM Corp.'s Internet Security System's X-Force threat analysis service. Enterprise administrators should also pay close attention to an SNMP (Simple Network Monitoring Protocol) patch issued Tuesday, Ollmann said. Microsoft has rated this patch as "important," rather than critical because SNMP is normally blocked at the firewall and turned off by default on Windows systems. However, it is widely deployed as part of the network monitoring infrastructure in the enterprise, and is often used on critical servers, Ollmann said. Ollmann believes this SNMP patch is the "most important" update for enterprise customers. "Since the service is widely deployed in the enterprise and since it's commonly deployed on servers, we think this would be an important attack vector for enterprises," he said. The remaining updates include a "critical" fix for Visual Studio 2005, and "important" updates for Windows and Outlook Express, Microsoft said. Microsoft defines "critical" flaws as bugs that could allow the propagation of an Internet worm without any action on the part of the victim. The company's next set of security updates are due Jan. 9.
