Injecting ASCII control characters into mail() arguments

Arbitrary ASCII control characters may be injected into string arguments of mail() function. If mail() arguments are takeon from user's input it may give the user ability to alter message content including mail headers.

Example of such a vulnerability:

http://www.php.net/mailling-lists.php?maillist=rcpt@foo.bar%0aFrom:%20spammer@oh.ah%0a%0aMAIL%20BODY%0a.%0a&email=a

:-)

PHP should do content filtering before creating message body sent with "sendmail -t" command.
