- ---------------------------------------------------------------------

1. Topic:

Updated PHP packages for Red Hat Linux 8.0 and 9 are available that fix a
number of bugs, as well as a minor security problem in the transparent
session ID functionality.

2. Relevant releases/architectures:

Red Hat Linux 8.0 - i386
Red Hat Linux 9 - i386

3. Problem description:

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

This update contains fixes for a number of bugs discovered in the version
of PHP included in Red Hat Linux 8.0 and 9.  These bugs include the use of 
a PHP script as an ErrorDocument and possible POST body corruption in some
configurations.

Also included is a fix for a minor security problem. In PHP version 4.3.1
and earlier, when transparent session ID support is enabled using the
"session.use_trans_sid" option, the session ID is not escaped before use. 
This allows a Cross Site Scripting attack.  The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CAN-2003-0442 to
this issue.

All users of PHP are advised to upgrade to these erratum packages, which
contain back-ported patches to correct 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 Red Hat Network.  Many
people find this an easier way to apply updates.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

5. Bug IDs fixed  (  for more info):

74761 - snmp module relocation error
