Dear BUGTRAQ@SECURITYFOCUS.COM,
I've updated "Bypassing content filtering software" whitepaper
http://www.security.nnov.ru/advisories/content.asp to include new way to
bypass content filtering software. It confirmed to work with NAV and not
to work with McAffee and KAV (AVP).
Symantec was contected via support@symantec.com and
symsecurity@symantec.com and didn't reply.
13.Case sensitivity of Content-Type and Content-Disposition
Most MUAs ignore case of Content-Type and Content-Disposition headres
while content filtering software may behave in different way. It makes
it possible to bypass content-filtering software by using header like
CONTENT-type: text/plain;

P.S. thanks to everyone on vuln-dev who participated in testing.
