Sloppy programming (really, there's no excuse for not including
bounds-checking when decoding)is a big part of the picture.  In Windows'
case, a lot of the vulnerabilities seem to be a combination of sloppy
coding and including "features" that have vulnerabilities inherent. (e.g.
OLE in browser applets, executables in email attachments...)  Of course, if
a set of object libraries with inherent vulnerabilities in them is used,
bugs get re-used too.

Cheers,
