Multiple integer overflows in the (1) createwbmp and (2) readwbmp functions in wbmp.c in the GD library (libgd) in PHP 4.0.0 through 4.4.6 and 5.0.0 through 5.2.1 allow context-dependent attackers to execute arbitrary code via Wireless Bitmap (WBMP) images with large width or height values.

The remote BIG-IP device is missing a patch required by a security advisory.

From Red Hat Security Advisory 2007:0155 :

Updated PHP packages that fix several security issues are now available for Red Hat Enterprise Linux 3 and 4.

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

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 processed data. If a remote attacker was able to pass arbitrary data to PHP's unserialize() function, they could possibly execute arbitrary code as the apache user. (CVE-2007-1286)

A flaw was found in the way the mbstring extension set global variables. A script which used the mb_parse_str() function to set global variables could be forced to enable the register_globals configuration option, possibly resulting in global variable injection.
(CVE-2007-1583)

A double free flaw was found in PHP's session_decode() function. If a remote attacker was able to pass arbitrary data to PHP's session_decode() function, they could possibly execute arbitrary code as the apache user. (CVE-2007-1711)

A flaw was discovered in the way PHP's mail() function processed header data. If a script sent mail using a Subject header containing a string from an untrusted source, a remote attacker could send bulk e-mail to unintended recipients. (CVE-2007-1718)

A heap based buffer overflow flaw was discovered in PHP's gd extension. A script that could be forced to process WBMP images from an untrusted source could result in arbitrary code execution.
(CVE-2007-1001)

A buffer over-read flaw was discovered in PHP's gd extension. A script that could be forced to write arbitrary string using a JIS font from an untrusted source could cause the PHP interpreter to crash.
(CVE-2007-0455)

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

According to its banner, the version of PHP 5.x installed on the remote host is older than 5.2.2.  It is, therefore, affected by multiple vulnerabilities:

  - A heap-based buffer overflow vulnerability was found     in PHP's gd extension. A script that could be forced to     process WBMP images from an untrusted source could     result in arbitrary code execution. (CVE-2007-1001)

  - A vulnerability in the way the mbstring extension     setglobal variables was discovered where a script using     the mb_parse_str() function to set global variables     could be forced to to enable the register_globals     configuration option, possibly resulting in global     variable injection. (CVE-2007-1583)

  - A context-dependent attacker could read portions of     heap memory by executing certain scripts with a     serialized data input string beginning with 'S:', which     did not properly track the number of input bytes being     processed. (CVE-2007-1649)

  - A vulnerability in how PHP's mail() function processed     email messages, truncating potentially important     information after the first ASCIIZ (\0) byte.
    (CVE-2007-1717)

  - A vulnerability in how PHP's mail() function processed     header data was discovered. If a script sent mail using     a subject header containing a string from an untrusted     source, a remote attacker could send bulk email to     unintended recipients (CVE-2007-1718).

A heap-based buffer overflow vulnerability was found in PHP's gd extension. A script that could be forced to process WBMP images from an untrusted source could result in arbitrary code execution (CVE-2007-1001).

A DoS flaw was found in how PHP processed a deeply nested array. A remote attacker could cause the PHP intrerpreter to creash by submitting an input variable with a deeply nested array (CVE-2007-1285).

The internal filter module in PHP in certain instances did not properly strip HTML tags, which allowed a remote attacker conduct cross-site scripting (XSS) attacks (CVE-2007-1454).

A vulnerability in the way the mbstring extension set global variables was discovered where a script using the mb_parse_str() function to set global variables could be forced to to enable the register_globals configuration option, possibly resulting in global variable injection (CVE-2007-1583).

A vulnerability in how PHP's mail() function processed header data was discovered. If a script sent mail using a subject header containing a string from an untrusted source, a remote attacker could send bulk email to unintended recipients (CVE-2007-1718).

Updated packages have been patched to correct these issues. Also note that the default use of Suhosin helped to protect against some of these issues prior to patching.

This Update fixes numerous vulnerabilities in PHP. Most of them were made public during the 'Month of PHP Bugs'. The vulnerabilities potentially lead to crashes, information leaks or even execution of malicious code.

CVE-2007-1380 / CVE-2007-0988 / CVE-2007-1375 / CVE-2007-1521 / CVE-2007-1376 / CVE-2007-1583 / CVE-2007-1461 / CVE-2007-1484 / CVE-2007-1700 / CVE-2007-1717 / CVE-2007-1718 / CVE-2007-1001 / CVE-2007-1824

CVE-2007-1380, CVE-2007-0988, CVE-2007-1375, CVE-2007-1454 CVE-2007-1453, CVE-2007-1521, CVE-2007-1522, CVE-2007-1376 CVE-2007-1583, CVE-2007-1460, CVE-2007-1461, CVE-2007-1484 CVE-2007-1700, CVE-2007-1717, CVE-2007-1718, CVE-2007-1001 CVE-2007-1824, CVE-2007-1889, CVE-2007-1900

The remote host is running a version of Mac OS X 10.4 or 10.3 which does not have the security update 2007-007 applied. 

This update contains several security fixes for the following programs :

 - bzip2
 - CFNetwork
 - CoreAudio
 - cscope
 - gnuzip
 - iChat
 - Kerberos
 - mDNSResponder
 - PDFKit
 - PHP
 - Quartz Composer
 - Samba
 - SquirrelMail
 - Tomcat
 - WebCore
 - WebKit

The remote host is affected by the vulnerability described in GLSA-200705-19 (PHP: Multiple vulnerabilities)

    Several vulnerabilities were found in PHP, most of them during the     Month Of PHP Bugs (MOPB) by Stefan Esser. The most severe of these     vulnerabilities are integer overflows in wbmp.c from the GD library     (CVE-2007-1001) and in the substr_compare() PHP 5 function     (CVE-2007-1375). Ilia Alshanetsky also reported a buffer overflow in     the make_http_soap_request() and in the user_filter_factory_create()     functions (CVE-2007-2510, CVE-2007-2511), and Stanislav Malyshev     discovered another buffer overflow in the bundled XMLRPC library     (CVE-2007-1864). Additionally, the session_regenerate_id() and the     array_user_key_compare() functions contain a double-free vulnerability     (CVE-2007-1484, CVE-2007-1521). Finally, there exist implementation     errors in the Zend engine, in the mb_parse_str(), the unserialize() and     the mail() functions and other elements.
  Impact :

    Remote attackers might be able to exploit these issues in PHP     applications making use of the affected functions, potentially     resulting in the execution of arbitrary code, Denial of Service,     execution of scripted contents in the context of the affected site,     security bypass or information leak.
  Workaround :

    There is no known workaround at this time.

Updated PHP packages that fix several security issues are now available for Red Hat Enterprise Linux 5.

New php packages are available for Slackware 10.2, 11.0, and -current to improve the stability and security of PHP. Quite a few bugs were fixed -- please see http://www.php.net for a detailed list. All sites that use PHP are encouraged to upgrade. Please note that we haven't tested all PHP applications for backwards compatibility with this new upgrade, so you should have the old package on hand just in case. Both PHP 4.4.7 and PHP 5.2.2 updates have been provided.

The remote host is running a version of PHP lower than 4.4.7 or 5.2.2.  This version is vulnerable to a number of remote issues.  At least one of these issues is related to a buffer overflow attack.  An attacker exploiting these flaws would be able to impact confidentiality, integrity, and availability.
