Virtual Administrator’s December 2013 Patch Recommendations

10 Security Bulletins were released – 5 Critical, 5 Important, and 0 Moderate

This Month In Brief

11 Security Bulletins were released 5 Critical, 6 Important

We have decided to deny KB2887069 (MS13-101) at this time.

There are a number of reports that anti-virus can interfere with KB2887069’s installation and the update gets stuck during the installation process. We have decided to wait until the problem is corrected before allowing it in our patch policy. KB2887069 is rated Important and per Microsoft An attacker must have valid logon credentials and be able to log on locally to exploit this vulnerability.

Of the 5 Critical patches this month MS13-096 and MS13-097 (KB2898785) should be your top priority. MS13-096 addresses what became known as the TIFF zero-day detailed in Microsoft Security Advisory (2896666). That vulnerability was discovered a few days before November’s Patch Tuesday and was not ready in time. MS13-097 patches a vulnerability in Internet Explorer 6, 7, 8, 9, 10, and 11. After your next patch cycle completes you should follow up and make sure these are installed.

For those keeping count Microsoft issued 106 total software update bulletins in 2013. This is up from the 83 we saw in 2012 but in line with the 100+ we’ve seen in previous years. So on average 100 bulletins per year is what we have seen and will most likely continue to see in upcoming years.
