CONECTIVA LINUX SECURITY ANNOUNCEMENT
PACKAGE : php4 SUMMARY : Problems with per-directory php directives and with virtual hosts DATE : 2001-01-18 13:52:00 ID : CLA-2001:373 RELEVANT RELEASES : 6.0
DESCRIPTION The php4 module shipped with Conectiva Linux 6.0 has two security problems that were recently made public by the PHP development team based on a report by James Moore:
1) It is possible to specify PHP directives on a per-directory basis under apache. In the vulnerable versions of PHP, a remote attacker could craft an HTTP request that would cause the next page to be served with the wrong values for these directives.
2) Even though PHP is installed, it can be deactivated and activated via a directive like "engine=off" or "engine=on". This directive can be used on a per-directory basis or even per virtual host. Vulnerable versions of the php4 module could "leak" the "engine=off" setting to other virtual hosts on the same machine, effectively disabling PHP for those hosts and resulting in PHP source code being sent to the client instead of being executed on the server.
3.0.x versions of the PHP module are not affected by these problems.
