According to its banner, the version of PHP 5.5.x installed on the remote host is a version prior to 5.5.9. It is, therefore, potentially affected by the following vulnerabilities related to the GD extension :
A heap-based buffer overflow error exists related to the functions ‘gdImageCrop’ and ‘imagecrop’ that could allow denial of service attacks and possibly arbitrary code execution. (CVE-2013-7226)
An error exists in the function ‘gdImageCrop’ related to return value checking that could lead to use of NULL pointers and denial of service attacks.
(CVE-2013-7327)
Multiple integer signedness errors exist in the function ‘gdImageCrop’ that could allow denial of service attacks and information disclosure.
(CVE-2013-7328)
A data type checking error exists that could allow information disclosure. (CVE-2014-2020)
Note that this plugin does not attempt to exploit these issues, but instead relies only on PHP’s self-reported version number.
