March 7, 2013

Mozilla has released a new version, 19.0.2, of the Firefox browser for Linux, Mac OS X, and Windows.  This is a security driven release, which provides a fix for a vulnerability [MFSA 2013-29] in the HTML editor component.  More information is available in the Release Notes.

Because of the security content of this release, I recommend that you update your systems as soon as you conveniently can.  You can use the update mechanism built into the browser (Help / About Firefox /Check for Updates), or you can download a complete installation package.

Microsoft Patch Tuesday Preview, March 2013

March 7, 2013

As is customary, Microsoft today released a preview of the security bulletins and associated patches that it intends to release next Tuesday, March 12.  The Security Bulletin Advanced Notification for March lists seven security bulletins for this month.  Two of these bulletins affect Windows and its components; one has a maximum severity rating of Critical, and the other is rated Important.  All supported versions of Windows are affected by at least one bulletin.  Another of the bulletins,, rated Critical, affects Microsoft’s Silverlight, including at least some installations of Silverlight on Mac systems.

The remaining four bulletins all affect Microsoft Office and its various components; two of these are rated Critical, and two Important. One of the Critical bulletins also affects Microsoft’s SharePoint server software.

According to Microsoft, the two Windows bulletins will require a system restart, and three of the Office bulletins may require one, depending on your system’s configuration.  Microsoft says that a restart will not be required for the Silverlight bulletin, and one of the Office bulletins.

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.
