Discussion

PHP GD Extension WBMP File Integer Overflow Vulnerabilities

PHP's GD extension is prone to two integer-overflow vulnerabilities because it fails to ensure that integer values aren't overrun.

Successfully exploiting these issues allows attackers to crash the affected application, potentially denying service to legitimate users. Due to the nature of the issues, code execution may also be possible, but this has not been confirmed.

PHP 5.2.1 and prior versions are vulnerable.

Exploit / POC

PHP GD Extension WBMP File Integer Overflow Vulnerabilities

The following C exploit creates a WBMP file sufficient to demonstrate denial-of-service attacks.

Using the following PHP code with the resulting WBMP file will crash PHP:

&lt;?php
$image = imagecreatefromwbmp('test.wbmp'); //overflow occurs
?&gt;

Solution / Fix

PHP GD Extension WBMP File Integer Overflow Vulnerabilities

Solution:
The vendor has committed patches to the PHP version-control system. Please see the references for more information. PHP 5.2.2 will likely contain the fix when it is released.
