Red Hat, Inc. Red Hat Security Advisory
Synopsis: Updated PHP packages are available
Advisory ID: RHSA-2002:035-13
Issue date: 2002-02-27

1. Topic:
Updated PHP packages are available to fix vulnerabilities in the functions
that parse multipart MIME data, which are used when uploading files
through forms.
2. Relevant releases/architectures:
Red Hat Linux 6.2 - alpha, i386, sparc
Red Hat Linux 7.0 - alpha, i386
Red Hat Linux 7.1 - alpha, i386, ia64
Red Hat Linux 7.2 - i386, ia64, s390
3. Problem description:
PHP is an HTML-embeddable scripting language. A number of flaws have been
found in the way PHP handles multipart/form-data POST requests. Each of
these flaws could allow an attacker to execute arbitrary code on the remote
system.
PHP 3.10-3.18 contains a broken boundary check (hard to exploit) and an
arbitrary heap overflow (easy to exploit). These versions of PHP were
shipped with Red Hat Linux 6.2.
PHP 4.0.1-4.0.3pl1 contains a broken boundary check (hard to exploit) and a
heap-off-by-one (easy to exploit). These versions of PHP were shipped with
Red Hat Linux 7.0.
PHP 4.0.2-4.0.5 contains two broken boundary checks (one very easy and one
hard to exploit). These versions of PHP were shipped with Red Hat Linux
7.1 and as erratas to 7.0.
PHP 4.0.6-4.0.7RC2 contains a broken boundary check (very easy to exploit).
These versions of PHP were shipped with Red Hat Linux 7.2
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2002-0081 to this issue.
If you are running PHP 4.0.3 or above, one way to work around these bugs is
to disable the fileupload support within your php.ini file (by setting
file_uploads = Off).
All users of PHP are advised to immediately upgrade to these errata
packages which close these vulnerabilities.
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.
After applying these updates you will need to restart your web server if it
was running before the update was applied.
