Unofficial Report: MS13-057 and Video Related Issues

by Carol~ Moderator / July 18, 2013 6:47 AM PDT

As far as I know the following hasn't been documented by Microsoft. It was brought to light by Susan Bradley.

She writes (Patch Watch update: Unexpected patch problems) on July 18th :

'Adding the updates from July's Patch Tuesday is turning out to be a bit rougher than expected.

Two updates that initially looked okay are causing problems with a small — at least for now — number of Windows systems.

MS13-057 (2803821, 2834904)

Some side effects from the Windows Media patch

As discussed in last week's Patch Watch, MS13-057 contains several critical patches for the Windows Media Format runtime, required for running Windows Media audio and video. Not long after two of those patches — KB 2803821 and KB 2834904 — showed up in Windows Update, users of Adobe Premiere Pro CS6, Camtasia Studio 8.1, and Serif MoviePlus X6 reported problems while editing videos. Images in the video preview screens were cut in half.

Both Adobe and TechSmith (the publisher of Camtasia Studio) are recommending that their customers uninstall KB 2803821 and KB 2834904. Although the patch applies to all current versions of Windows, the problems seem to impact primarily XP and Win8 systems.

For more information, see the thread on Adobe's Premiere Pro forum and/or TechSmith's support page.

-What to do: Microsoft is investigating the issue and might release an updated version of the security patch. There are no reports of active attacks using the vulnerabilities in KB 2803821 and KB 2834904 (MS13-057), and other media apps might be adversely affected by the two patches. So I'm changing my recommend from "install" to either not installing or uninstalling them. (Note: If you uninstall either update but leave Windows Update's automatic updating on, the patches will automatically reinstall.) '
