Detail

Problem Description:

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 important 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.

A denial of service flaw was found in the way PHP processed a deeply nested array. A remote attacker could cause the PHP interpreter to crash by submitting an input variable with a deeply nested array. (CVE-2007-1285)

A flaw was found in the way PHP's unserialize() function processes data. If a remote attacker is able to pass arbitrary data to PHP's unserialize() function, it may be possible for them to execute arbitrary code as the apache user. (CVE-2007-1286)

A double free flaw was found in PHP's session_decode() function. If a remote attacker is able to pass arbitrary data to PHP's session_decode() function, it may be possible for them to execute arbitrary code as the apache user. (CVE-2007-1711)

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

5. Bug IDs fixed (http://bugzilla.redhat.com/):

235225 - CVE-2007-1285 Multiple "Month of PHP Bugs" PHP issues (CVE-2007-1286, CVE-2007-1711)

Id Description
33946 PHP session_decode() Double-free Arbitrary Code Execution

PHP contains a flaw that may allow a context-dependent attacker to elevate privileges. The issue is due to the unserializer not properly validating user-supplied input. By passing crafted data, an attacker can overwrite variables pointing to the GLOBALS array or the session data in _SESSION allowing for the execution of arbitrary code.
32771 PHP unserialize() ZVAL Reference Counter Remote Overflow

PHP contains a flaw that may a context-dependent attacker to elevate privileges. The issue can occur when the unserialize() function is used on an attacker supplied string, which can result in an integer overflow in the refcount variable in _zval_struct through the creation of a large number of references for a specific variable leading to a double destruction of the underlying variable. It is possible that the flaw may allow a remote attacker to execute arbitrary code resulting in a loss of integrity.
32769 PHP Zend Engine Variable Destruction Deep Recursion Overflow

Zend Engine I in PHP 4.4.6 and lower, and Zend Engine II in PHP versions 5.2.1 and lower, contain flaws that may allow a remote denial of service. The issue is due to the application not enforcing sanity checks for the depth of nested arrays which allows a remote user to create very deeply nested array structures. Since the destruction of PHP arrays is done in a recursive way, the attempted destruction of the user's deeply nested array will result in a crash when the stack limit is exhausted, leading to a loss of availability for the service.
