PHP: buffer overflow of imagecrop
Synthesis of the vulnerability
An attacker, who can transmit parameters to the imagecrop() function, can generate a buffer overflow of PHP, in order to trigger a denial of service, and possibly to execute code.Impacted products: MBS

Description of the vulnerability
Since PHP 5.5.0, the imagecrop() function is used to cut an image, using for example the following dimensions:
$dimensions = array("x" => 10, "y" => 10, "width" => 50, "height" => 50);
However, if the position ("x") of the rectangle to cut is greater than the size of the image, an overflow occurs.
An attacker, who can transmit parameters to the imagecrop() function, can therefore generate a buffer overflow of PHP, in order to trigger a denial of service, and possibly to execute code.Complete Vigil@nce bulletin....
