    Keep Calm and Patch On This Patch Tuesday

    Microsoft released eight security bulletins this Patch Tuesday. At first glance, that may seem like a high number but the good news is, at this time, none of the vulnerabilities have been under active attack. While three bulletins are considered critical, with the balance important, two should be your top priority, according to Paul Henry, security and forensics analyst, Lumension

    Year-to-date, Microsoft has released 65 security bulletins. For anyone keeping track, that’s seven more than what we had covered off on last year at this time. At the start of the year, we anticipated higher numbers in 2013, given Microsoft’s commitment to cleaning up the low hanging fruit out there. Last year at this time, there were 35 important patches issued; we now see 40. Our criticals in 2013 so far number 25, with 35 in total for 2012. Good news there!

    Microsoft is also releasing a framework for improved cryptography. It allows customers more fidelity in managing cryptographic algorithms and digital certificates. Separately, they are also offering a new package for disabling support for MD5 hashes. You’ll need to go get them in the download center for now – they won’t be pushed out as a new standard until next year.

    Outside of Microsoft, a flaw in Google’s Chrome browser was reported last week. It allows passwords saved in the browser to be published in the clear – free for the taking. If you use Chrome, you should first go to chrome://settings/passwords and delete them. Then, you should remember never to save passwords in a browser.
