Next scheduled release: August 11th, 2012
The heads up for this month is; On Tuesday 11th August (US time; Wednesday 12th August AU time) Microsoft expect to release two (2) bulletins each of which have a maximum rating of Important.
Hello there. As we prepare for September’s two security updates, we’d like to remind you about an important change to Windows’ certificate requirements included in Security Advisory 2661254 (Update For Minimum Certificate Key Length). In June, we began communicating this change, which will help improve security across the Windows platform by increasing the requirement for certificates used in Public Key Infrastructure (PKI) to an RSA key length minimum of 1024 bits. By raising the bar of our certificate requirements, as part of our ongoing work to evaluate Microsoft’s security efforts and make improvements, we aim to help create a safer more trusted Internet for everyone.
Onward to our September Advance Notification Service announcement for this month. September has historically been a light month for security updates, and this month we have two Important-class bulletins addressing four issues in Visual Studio Team Foundation Server and System Center Configuration Manager. As usual, the bulletin release is scheduled for the second Tuesday of the month, Sept. 11, 2012, at approximately 10 a.m. PDT.
