security patch

Hi webmaster, I know you are not the man who can reply to this (probably the mailing list is more suitable for this type of mail), but in fact I just have a small question and I lack time to subscribe to ml, read all reply, and unsubscribe then... ... so sorry for inconvenience. I saw that you put a new "security patch" for php 4.3.0 (and probably <= release), I am an user of php 4.3.0 (coupled with apache of course), and I am a bugtraq reader. I can't remember any public issue about this bug, so I am questionning myself if you don't officialy disclose this bug because an attacker can't exploit it... and so... Have I to patch my php 4.3.0, or is this bug not really important ? (something as log apache child segfault in the worth case).. Thanks for reply, and one again sorry for lost time due to this mail. Best regard, Nicolas Brito
