CONECTIVA LINUX SECURITY ANNOUNCEMENT 
- --------------------------------------------------------------------------

PACKAGE   : php4
SUMMARY   : Remote arbitrary code execution vulnerabilities and other
DATE      : 2004-07-16 11:56:00
ID        : CLA-2004:847
RELEVANT
RELEASES  : 8, 9, 10

DESCRIPTION
 PHP[1] is a very popular scripting language used by web servers to
 offer dynamic content.
 
 Stefan Esser noted[2] a vulnerability[3] in php code so that a remote
 attacker could force php to hit memory_limit in unsafe places which
 would lead to a possible execution of arbitrary code.
 
 He also found[4] out that the strip_tags() function, often used as a
 validator for user input, could allow tags containing the null char.
 
 This announcement also fixes the misinstalation of the CLI interface
 instead of the CGI one. Thanks to Willian Marcelo Piovezan for the
 report[5].


SOLUTION
 It is recommended that all PHP users upgrade their packages.
 
 
 IMPORTANT
 If PHP 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.)
 
 # service httpd start
