Microsoft Patches DNS Zero-Day Vulnerability

On May 8, 2007, Microsoft patched 19 flaws alongside seven vital updates, tackling a zero-day DNS server bug, and glitches in Microsoft Exchange, Microsoft Excel, Internet Explorer, Office and Word.

Never before, has every patch released by Microsoft's monthly Patch Tuesday incident been considered vital, implying that since they are distantly executable and that executives should strive to install them immediately - right after assessing them for platform independence with present systems and programs.

Microsoft Security Bulletin MS07-029 is perhaps the severest of the seven fixes released on May 8, 2007. This fix repairs the zero-day DNS bug that cyber-terrorists have been using since April 13, 2007.

The DNS Server Service glitch, though slightly affected of late, has been troubling some IT professionals as DNS servers match domain names to the real IP addresses of the Web browsers hosting the required websites.

Kraft Foods ex worldwide security manager Rich Linke, and a Chicago based autonomous security consultant said, security experts would probably begin fixing Exchange server and installing the latest version of zero-day DNS server. Holes in Internet Explorer and Excel also could create problems from an installation viewpoint, and be a big improvement for the PC, Linke stated, as reported on May 8, 2007 by Searchsecurity.Techtarget.

Microsoft also released fixes securing four dangerous flaws in Internet Explorer that could be used by a hacker when user tours a malevolent site. Both IE 6 and 7 have bugs and also contain a Property Type Memory Corruption Flaw plus HTML Objects Memory Corruption.

"According to the latest Internet Security Threat Report, hackers are sustaining the exploitation of browser and program flaws and social engineering techniques to infiltrate PCs to execute malware," alleged Oliver Friedrichs, Symantec Security Response's director of emerging technologies, as reported by May 8, 2007 edition of Searchsecurity.Techtarget .

Microsoft advises that all these improvements should be implemented directly. It also issued new adaptations of the malware Elimination Device and various urgent non-security versions containing update for the Outlook spam filter, a PowerPoint update permitting executives to limit the types of presentations that can be opened and a " dependability update" for Windows XP.
