Critical PHP bug - act ASAP if you are running web with sensitive data

[Tõnu Samuel <tonu () jes ee>]

Hi everybody!

I want to tell that pretty nasty bug was discovered in PHP (all tested 
versions were vulnerable). I do not want to disclose much details as it may 
hurt many websites. I expect PHP team to make patch first.

There is simple way to protect yourself against this bug if you put some code 
in beginning of every source code looking for weird ASCII bytes before any 
other code. Make some kind of "white-list" for characters you allow and deny 
everything else.

More details to come when we have PHP patches distributed with major 
distributions. I might disclose details before to some IDS vendor or other 
trusted party.
