RE: [Full-disclosure] URI handling woes in Acrobat Reader, Netscape, Miranda, Skype

Hey.

I've been waiting to see when somebody finally got around to testing
Outlook express. 

It's also possible to exploit this through Outlook full version from
office 2003. 

I have also discovered other problems (not difficult to fine) which
allows the execution of any program which has registered as a 
document handler, with the URL been passed to it. 

This gets interesting when the local application has problems such
as a command line buffer overflow.

I'm guessing this is similar to what has been documented here.
