Red Hat Security Advisory
Synopsis: Moderate: php security update
Advisory ID: RHSA-2007:0888-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2007-0888.html
Issue date: 2007-10-23
Updated on: 2007-10-23
Product: Red Hat Enterprise Linux
CVE Names: CVE-2007-2509 CVE-2007-2872 CVE-2007-3799
CVE-2007-3996 CVE-2007-4670
- ---------------------------------------------------------------------
1. Summary:
Updated PHP packages that fix several security issues are now available for
Red Hat Enterprise Linux 2.1
This update has been rated as having moderate security impact by the Red
Hat Security Response Team.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64
Red Hat Linux Advanced Workstation 2.1 - ia64
Red Hat Enterprise Linux ES version 2.1 - i386
Red Hat Enterprise Linux WS version 2.1 - i386
3. Problem description:
PHP is an HTML-embedded scripting language commonly used with the Apache
HTTP Web server.
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 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)
A flaw was found in the PHP 'ftp' extension. If a PHP script used this
extension to provide access to a private FTP server, and passed untrusted
script input directly to any function provided by this extension, a remote
attacker would be able to send arbitrary FTP commands to the server.
(CVE-2007-2509)
Users of PHP should upgrade to these updated packages which contain
backported patches to correct these issues.
