[Snort-sigs] Mime type filtering when looking for GDI+

FYI only
I noticed on incidents.org that Judy Novak created some snort sigs the
other day (Spet 22) to detect malicious jpegs. I thought everyone should
know that the mime type/content type they look for is 'image/jp*'. But
the world needs to be aware that "image/pjp*" is also a valid mime type
for jpegs. Matter of fact, I've been seeing a lot of "image/pjpeg" files
traversing our perimeter. Where this mime type comes from is a mystery
as it is not listed in some of the HTTP resources I've searched. Rumor
has it that Japanese IIS servers generate this mime type, but as I said,
it is rumor.
