Adobe Reader vs Win 8 Reader security-wise

I've been using the Windows 8 pdf Reader app instead of installing Adobe Reader. While Adobe Reader gets updated fairly frequently, it seems like there has only been one update to the Windows 8 Reader app. Does anyone know if Reader is vulnerable to the exploits that keep dogging Adobe Reader? Or do exploits need to be written specifically targeting Win 8 Reader? I've not read anything that indicates people have been targeting it yet.

Thanks

 

No the Windows 8 reader app is not vulnerable to those exploits, furthermore it is sandboxed using AppContainer.

Adobe reader has a lot more features than the Windows 8 reader, but a lot of those features are debatably useless to a majority of people. I'd recommend sticking with the Windows reader unless there is a feature you're missing.

Of note is that there's also an "Adobe Reader Touch" app for Windows 8, I have not personally tried it.

 

OK thanks. I've just done some reading on AppContainer, that seems like a real improvement, if it works as intended.
