It's a security issue, i found it and reported this to MS long time ago when i started to research shared sections bugs, MS will fix the issue in some future. I don't know why MS said to you that it's not a security issue. Cesar. --- sylvain.roger () solucom fr wrote:
As I got some questions about this I think I need to precise it. I can say for sure now : It is not a firefox vulnerability but Microsoft Office vulnerability. Firefox is just here as an example. The vulnerability is that when a winword.exe process is created from another application (like firefox.exe) it creates a shared section called \BaseNameObjects\Mso97SharedDgXXXXXXXX which has write rights for everyone. This allows to write arbitrary data on the shared section resulting in a denial of service of all opened Microsoft Office applications. It may be necessary sometimes to reboot the machine in order to use again the Office applications. Microsoft just answers it is a technical issue and not a security issue
