I believe .ICOs are blocked due to a Microsoft vulnerability  Something
about a divide-by-zero overflow.  Ah, here it is.
http://www.kb.cert.org/vuls/id/290961

Quote from the page:
"There is an integer division by zero vulnerability in the way the ICO
parsing component of GDI+ (Gdiplus.dll) handles ICO files with a
Heightvalue of zero in the
InfoHeader section of the ICO file. By introducing a specially crafted ICO
file to the vulnerable component, a remote attacker could trigger an
integer division by zero denial-of-service condition.


I imagine a simple filter could be written that checks that none of the
dimensions are declared "0"."  Of course, I can say it's simple because I
am not the one coding it  ;-)  .
