"Updated php packages that fix various security issues are now
available.

PHP is an HTML-embedded scripting language commonly used with the
Apache HTTP server.

Stefan Esser discovered a flaw when memory_limit configuration setting
is enabled in versions of PHP 4 before 4.3.8. If a remote attacker
could force the PHP interpreter to allocate more memory than the
memory_limit setting before script execution begins, then the attacker
may be able to supply the contents of a PHP hash table remotely. This
hash table could then be used to execute arbitrary code as the
'apache' user. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2004-0594 to this issue.

This issue may be exploitable if using the default PHP configuration
with the 'register_globals' setting of 'On'. The Apache memory
exhaustion bug, fixed in a previous update to Red Hat Enterprise Linux
3, may also allow this PHP issue to be exploited; this Apache bug does
not affect Red Hat Enterprise Linux 2.1.

Stefan Esser discovered a flaw in the strip_tags function in versions
of PHP before 4.3.8. The strip_tags function is commonly used by PHP
scripts to prevent Cross-Site-Scripting attacks by removing HTML tags
from user-supplied form data. By embedding NUL bytes into form data,
HTML tags can in some cases be passed intact through the strip_tags
function, which may allow a Cross-Site-Scripting attack. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
name CVE-2004-0595 to this issue.

All users of PHP are advised to upgrade to these updated packages,
which contain backported patches that address these issues."
