Red Hat, Inc. Red Hat Security Advisory
Synopsis: Updated PHP packages available
Advisory ID: RHSA-2003:017-06
Issue date: 2003-01-21
Updated on: 2003-02-04
Product: Red Hat Linux
Keywords: PHP wordwrap
Cross references:
Obsoletes:
CVE Names: CAN-2002-1396
---------------------------------------------------------------------
1. Topic:
Updated PHP packages are available that fix a vulnerability in the
wordwrap() function and a number of compatibility bugs.
2. Relevant releases/architectures:
Red Hat Linux 8.0 - i386
3. Problem description:
PHP is an HTML-embedded scripting language commonly used with the Apache
HTTP server.
A heap-based buffer overflow was found in the wordwrap() function in PHP
versions after 4.1.2 and before 4.3.0. If wordwrap() is used on
user-supplied input this could allow remote attackers to cause a denial of
service or execute arbitrary code.
Red Hat Linux 8.0 shipped with a version of PHP that was vulnerable to this
issue. Other Red Hat Linux distributions shipped with an earlier version
of PHP and are not vulnerable to this issue.
In addition, a number of compatiblity bugs have also been found between PHP
4.2 and Apache 2.0.
All users of PHP are advised to upgrade to these erratum packages which
contain a patch 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 (http://bugzilla.redhat.com/bugzilla for more info):
74396 - safe mode not working in php-4.2.2-8.0.5
75029 - PHP with Apache 2.0: getlastmod function fails
75712 - php4 with apache 2, getenv(ANYTHING) returns blank string
75878 - Apache caches requests by default, or there is some bug around.
78586 - Invalid command php_flag
