User Rating:      How can I rate this item?
Posted by Benjamin D. Thomas   
RedHat Linux Updated PHP packages that fix several security issues are now available for Red Hat Application Stack. Various integer overflow flaws were found in the PHP gd extension. A script that could be forced to resize images from an untrusted source could possibly allow a remote attacker to execute arbitrary code as the apache user. This update has been rated as having moderate security impact by the Red Hat Security Response Team.

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

1. Summary:

Updated PHP packages that fix several security issues are now available for
Red Hat Application Stack.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Application Stack v1 for Enterprise Linux AS (v.4) - i386, x86_64
Red Hat Application Stack v1 for Enterprise Linux ES (v.4) - i386, x86_64

3. Problem description:

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

These updated packages address the following vulnerabilities:

Various integer overflow flaws were found in the PHP gd extension. A
script that could be forced to resize images from an untrusted source could
possibly allow a remote attacker to execute arbitrary code as the apache
user. (CVE-2007-3996)

An integer overflow flaw was found in the PHP chunk_split function. If a
remote attacker was able to pass arbitrary data to the third argument of
chunk_split they could possibly execute arbitrary code as the apache user.
Note that it is unusual for a PHP script to use the chunk_script function
with a user-supplied third argument. (CVE-2007-2872)

A previous security update introduced a bug into PHP session cookie
handling. This could allow an attacker to stop a victim from viewing a
vulnerable web site if the victim has first visited a malicious web page
under the control of the attacker, and that page can set a cookie for the
vulnerable web site. (CVE-2007-4670)

A flaw was found in the PHP money_format function. If a remote attacker
was able to pass arbitrary data to the money_format function this could
possibly result in an information leak or denial of service. Note that is
is unusual for a PHP script to pass user-supplied data to the money_format
function. (CVE-2007-4658)

A flaw was found in the PHP wordwrap function. If a remote attacker was
able to pass arbitrary data to the wordwrap function this could possibly
result in a denial of service. (CVE-2007-3998)

A bug was found in PHP session cookie handling. This could allow an
attacker to create a cross-site cookie insertion attack if a victim follows
an untrusted carefully-crafted URL. (CVE-2007-3799)

An infinite-loop flaw was discovered in the PHP gd extension. A script
that could be forced to process PNG images from an untrusted source could
allow a remote attacker to cause a denial of service. (CVE-2007-2756)

Users of PHP should upgrade to these updated packages which contain
backported patches to correct these issues.

4. Solution:

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

This update is available via Red Hat Network.  Details on how to use 
the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/FAQ_58_10188
