Detail

Problem Description:

Updated php packages that fix various security issues are now available.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Desktop version 3 - i386, x86_64 Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64

3. Problem description:

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

Stefan Esser discovered a flaw when memory_limit is enabled in versions of PHP 4 before 4.3.8. If a remote attacker could force the PHP interpreter to allocate more memory than the memory_limit setting before script execution begins, then the attacker may be able to supply the contents of a PHP hash table remotely. This hash table could then be used to execute arbitrary code as the 'apache' user. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0594 to this issue.

This issue has a higher risk when PHP is running on an instance of Apache which is vulnerable to CAN-2004-0493. For Red Hat Enterprise Linux 3, this Apache memory exhaustion issue was fixed by a previous update, RHSA-2004:342. It may also be possible to exploit this issue if using a non-default PHP configuration with the "register_defaults" setting is changed to "On". Red Hat does not believe that this flaw is exploitable in the default configuration of Red Hat Enterprise Linux 3.

Stefan Esser discovered a flaw in the strip_tags function in versions of PHP before 4.3.8. The strip_tags function is commonly used by PHP scripts to prevent Cross-Site-Scripting attacks by removing HTML tags from user-supplied form data. By embedding NUL bytes into form data, HTML tags can in some cases be passed intact through the strip_tags function, which may allow a Cross-Site-Scripting attack. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0595 to this issue.

All users of PHP are advised to upgrade to these updated packages, which contain backported patches that address these issues.

4. Solution:

Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command:

up2date

For information on how to install packages manually, refer to the following Web page for the System Administration or Customization guide specific to your system:

Open Source Vulnerability Database (OSVDB)

Id Description
7871 PHP strip_tags() Function Filter Bypass

PHP strip_tags() function contains a flaw that may allow a malicious user to conduct a cross site scripting attack. The issue is triggered when the strip_tags()function fails to strip obfuscated HTML tags. It is possible that the flaw may result in a loss of integrity.
7870 PHP memory_limit Function Arbitrary Code Execution

The PHP memory_limit function contains a flaw that may allow a malicious user to remotely execute arbitrary code. The issue is triggered when an attacker is able to trigger the memory_limit abort within the zend_hash_init() function. It is possible that the flaw may allow the attacker to control the heap, resulting in a loss of confidentiality, integrity, and/or availability.
7269 Multiple HTTP Server Input Header Folding DoS

Apache contains a flaw that may allow a remote denial of service. The issue is triggered when overly long header lines starting with either a TAB or SPACE character are processed by the "ap_get_mime_headers_core()" function, and will result in loss of availability for the service.
