Hellow Guys, How are you?

I search in kernel archives and Changelogs for information about the
syncookies firewall breaking problem , where one person can bypass the
firewall in one machine with TCP SYNCOOKIES enabled and where the firewall
are based on SYN filtering to block only incoming TCP connections, but let
outgoing connections pass.

The lastest stable version of kernel 2.4.17 have it corrected?
If yes, in which version of kernel it are corrected?
If not, when it will be corrected?


Thanks a lot for attention and sorry for my poor English.
