The last few Patch Tuesday’s have been a bit heavier than usual, but December is poised to break the record again with 17 Bulletins being issued addressing 40 separate vulnerabilities. Before you panic however you should know that only two of the vulnerabilities are rated as “critical”, with all but one of the remaining flaws falling into the “important” category. A critical flaw is anything that allows for remote code execution so even one is bad enough, but at least we won’t have to wait too much longer for a fix.
The vulnerabilities are addressing every version of Windows from XP all the way to 7 (including server), as well as all supported versions of Office. A full list of the bulletins can be found on Microsoft TechNet , along with details of a webcast scheduled for Wednesday to address any questions.
Long story short this isn’t a patch Tuesday you would want to skip.
