DESCRIPTION
PHP[1] is a very popular scripting language used by web servers to
offer dynamic content.
This announcement fixes seven vulnerabilities[2] found by Stefan
Esser and four other vulnerabilities. For further information, please
refer to php4's changelog[3].
SOLUTION
It is recommended that all PHP4 users upgrade their packages.
IMPORTANT:
If PHP4 is being used as an Apache module, the web server has to be
restarted after the upgrade if it was already running. To do so,
please run, as root:
# service httpd stop
(wait a few seconds and check with "ps ax|grep httpd" if there are
any httpd processes running. On a busy webserver this could take a
little longer.)
