"Patch Tuesday" - April 2013
"Patch Tuesday" is the day each month that Microsoft releases their newest security updates, typically the second Tuesday of the month. This month included nine updates, including two "critical" updates affecting Windows and Internet Explorer and seven "important" updates. The updates impact Internet Explorer, Windows, Office... just about all users are affected:
For a full breakdown, check out the Microsoft Security Bulletin posted on line. Note that in the days leading up to Patch Tuesday, there is always an advance notification, which gets replaced by the actual bulletin on the release date. We're expecting to see the detailed notification later today. Read more of what's expected on ZDNet.
A "critical" patch is defined by Microsoft as "a vulnerability whose exploitation could allow the propagation of an Internet worm without user action". As a general rule, all critical patches should be installed as soon as possible. Also, if you have a managed service support plan with us, all patches are tested before installation, and we are tracking the updates for you.
Note that several of the security bulletins require reboots! If you aren't regularly rebooting your systems, this is an important reminder. |
