Application testing firm ChangeBASE says Microsoft security update MS08-052, which is designed to tackle security vulnerabilities in Microsoft Windows GDI+, may not work properly with a variety of applications.
Applications potentially affected include Reuters Messaging, Microsoft Messenger, Macromedia Dreamweaver and Microsoft Digital Image.
MS08-052 includes an update to a core element of the operating system (GDIPLUS.DLL). This file is part of the graphics library for Window XP.
A number of applications contain this file in their application installation routine, which could cause application compatibility issues when these packages are deployed.
Several applications ChangeBASE ran through its testing procedures can load a version of this file from their source media/download process when they are installed.
There is therefore a danger that if this happens, the installation will result in an out-of-date version of this file being loaded, and overwriting the version in the patch update this month.
ChangeBASE said IT departments need to identify which applications can do this and have a process in place to stop this from happening.
