Description
If an application that generates HTTP responses using the cgi gem with
untrusted user input, an attacker can exploit it to inject a malicious
HTTP response header and/or body.
Also, the contents for a CGI::Cookie object were not checked properly. If
an application creates a CGI::Cookie object based on user input, an
attacker may exploit it to inject invalid attributes in Set-Cookie header.
Such applications are unlikely, but a change is included to check
arguments for CGI::Cookie#initialize preventatively.
