Hello Kurt, Steve, vendors,

a security flaw was found in the way CGI.pm, a Perl module to 
handle Common Gateway Interface requests and responses, performed 
sanitization of values to be used for Set-Cookie and P3P headers. 
If a Perl CGI.pm module based CGI application reused cookies
values and accepted untrusted input from web browser(s), a remote
attacker could use this flaw to in an unauthorized way alter member
items of the cookie or add new items.
