SynopsisThe remote host is missing a vendor-supplied security patch
DescriptionThe remote host is missing the patch for the advisory SUSE-SA:2004:021 (php4/mod_php4).
PHP is a well known, widely-used scripting language often used within web server setups.
Stefan Esser found a problem with the 'memory_limit' handling of PHP which allows remote attackers to execute arbitrary code as the user running the PHP interpreter. This problem has been fixed. Additionally a problem within the 'strip_tags' function has been found and fixed which allowed remote attackers to inject arbitrary tags into certain web browsers, issuing XSS related attacks.
Since there is no easy workaround except disabling PHP, we recommend an update for users running the PHP interpreter within the apache web server.
To be sure the update takes effect you have to restart the apache process by executing the following command as root:
or if you use the apache2 package
Please download the update package for your distribution and verify its integrity by the methods listed in section 3) of this announcement.
Then, install the package using the command 'rpm -Fhv file.rpm' to apply the update.
