Highlights of the batch, which collectively address 21 vulnerabilities, include a critical update for Internet Explorer.
There are also two critical fixes for Windows itself, plus one for Microsoft’s .NET framework. Three the five remaining “important” fixes grapple with remote code execution-type vulnerabilities, one of which involves Office. Flaws of this type are best addressed sooner rather than later because they might easily be exploited by malware slingers.
Patching IE ought to be be the highest priority, according to vulnerability scanning and web services firm Qualys.
“[W]e saw last month how quickly attackers are incorporating browser-based attacks into their toolkits; an exploit for MS12-004 was detected a mere 15 days after Patch Tuesday,” notes Wolfgang Kandek, CTO of Qualys, in a blog post on the upcoming patch batch.
Andrew Storms, director of security operations at net security firm nCircle, said all supported versions of Windows will need patching. Oddly the most recent versions of Windows – which normally need the least patching – are the most affected by the February 2012 patch batch, he added.
“Microsoft is planning to deliver a big ‘Valentine’ next Tuesday. Their advance notification indicated they plan to release nine bulletins, and 21 CVEs next Tuesday. This is very consistent with last year’s ‘Valentine delivery’ that included 12 bulletins and 22 CVEs.”
“It’s surprising that this month’s patch affects almost every Windows operating system – each OS is affected by five of the eight applicable bulletins. That’s kind of weird because newer OS versions are generally more secure.”
“It’s even more surprising that Windows Server 2008 R2 is affected by the greatest number of bulletins. Generally, we see fewer bugs on server side operating systems, and this is doubly true for Server 2008 since so many of its newer mitigations and default settings protect the OS even when bugs are found,” he added.
