PHP Vulnerability Announced

corz writes "Just when you thought you were finished upgrading the webserver, 'The PHP Group has learned of a serious security vulnerability in PHP versions 4.2.0 and 4.2.1. An intruder may be able to execute arbitrary code with the privileges of the web server. This vulnerability may be exploited to compromise the web server and, under certain conditions, to gain privileged access.' Here's the bugtraq announcement." The hole is in the parsing of HTTP POST headers and can allow arbitrary code to be run on vulnerable machines. PHP thoughtfully decided to release a new version, 4.2.2, today with the fix. You can find a copy of it here (mirror).

The PHP Group has learned of a serious security vulnerability in PHP versions 4.2.0 and 4.2.1.

I can understand a certain amount of vulnerability after 420...

X86 Linux?

According to the announcements the only thing the vulnerability can do is cause your webserver to crash.
