Microsoft Patch Tuesday Preview, April 2013

April 4, 2013

In keeping with its usual schedule, Microsoft today released the Security Bulletin Advanced Notification for April 2013, previewing the security bulletins and associated patches it intends to release next Tuesday, April 9, 2013.  This month there are nine bulletins in all; two of these have a maximum security rating of Critical; the rest are rated Important.   Six of the bulletins, including both the Critical ones, are for Windows and its components.  All supported desktop versions of Windows have at least one Critical bulletin.  The table below shows a breakdown of the Windows bulletins by severity and Windows version.

Windows Version Critical Important Moderate Low
Windows XP+SP3 2 3 1
Windows Vista 2 2 1 1
Windows Server 2003 4 2
Windows Server 2008 3 3
Windows 7 2 2 1
Windows Server 2008 R2 3 2
Windows 8 1 2 1
Windows RT 1 2
Windows Server 2012 3 1
Windows Server Core 3 1

Microsoft says that five of the Windows bulletins will definitely require a restart, and the other bulletin may require one, depending on your system’s configuration.

The remaining three bulletins, all of which are rated important, app,ly to other Microsoft software products.   There will be two bulletins that affect SharePoint Server.  Groove, SharePoint Foundation, Office Web Apps, and Windows Defender for Windows 8 and RT are affected by one bulletin each.  The patch for Windows Defender will require a system reboot, and the others may require one.

As always, this information is subject to change between now and the actual release of the bulletins next Tuesday.  I will post a note here once the actual updates are available.

Mozilla Releases Thunderbird 17.0.5

April 4, 2013

In addition to releasing the new version 20 of Firefox, the Mozilla organization has released a new version, 17.0.5, of the Thunderbird E-mail client for Windows, Linux, and Mac OS X.   The new version includes fixes for eight identified security vulnerabilities, threeof which Mozilla rates as critical.  (These vulnerabilities also affected Firefox, and were fixed in release 20; the two applications share a considerable amount of code.)   This version also includes a bug fix for a font size adjustment issue.  More details are available in the Release Notes.

Because of the security fixes incorporated in this release, I recommend that you update your systems as soon as you conveniently can.  You can use the update mechanism built into the software (Help / About Thunderbird / Check for Updates), or you can get a complete installation package, in a variety of languages, from the Thunderbird download page.
