-----------------------------------------------------------------------
               Fedora Legacy Update Advisory

Synopsis:          Updated php packages fix security issues
Advisory ID:       FLSA:1868
Issue date:        2004-10-07
Product:           Red Hat Linux
Keywords:          Bugfix
Cross references:  https://bugzilla.fedora.us/show_bug.cgi?id=1868
CVE Names:         CAN-2004-0594 CAN-2004-0595
-----------------------------------------------------------------------


-----------------------------------------------------------------------
1. Topic:

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.

2. Relevant releases/architectures:

Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386

3. Problem description:

Stefan Esser discovered a flaw when memory_limit 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 CAN-2004-0594 to this issue.

This issue has a higher risk when PHP is running on an instance of
Apache which is vulnerable to CAN-2004-0493. It may also be possible to
exploit this issue if using a non-default PHP configuration with the
"register_defaults" setting is changed to "On".

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 CAN-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.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade.  Only those
RPMs which are currently installed will be updated.  Those RPMs which
are not installed but included in the list will not be updated.  Note
that you can also use wildcards (*.rpm) if your current directory *only*
contains the desired RPMs.

Please note that this update is also available via yum and apt.  Many
people find this an easier way to apply updates.  To use yum issue:

yum update

or to use apt:

apt-get update; apt-get upgrade

This will start an interactive process that will result in the
appropriate RPMs being upgraded on your system.  This assumes that you
have yum or apt-get configured for obtaining Fedora Legacy content.
Please visit http://www fedoralegacy.org/docs for directions on how to
configure yum and apt-get.
