Viruses exploit Microsoft patch cycle
The creators of the latest MyDoom variant, which exploits a recently discovered iFrame vulnerability in Internet Explorer, may have timed the release of the viruses to throw Microsoft's monthly patch cycle into disarray, security experts say.
In its latest monthly update on Tuesday, Microsoft was not able to fix a serious vulnerability in the Internet Explorer browser because the flaw was discovered only a few days before the company's regular update was due. The two variants of the MyDoom virus were released earlier this week, leaving the software giant without any option but to ignore the problem--for now.
Sean Richmond, senior technology consultant at Sophos Australia, told ZDNet Australia that it would have been impossible for Microsoft to create and test a reliable patch in four days--the time between the vulnerability being published and Tuesday's patch update.
"To release a stable patch for IE would be impossible (in that time) because they want to test it thoroughly before it goes out," Richmond said. "The monthly patch cycle was designed to make it easier for system administrators to schedule their updates, but a few days is just not enough time for Microsoft create and test a patch."
