Synopsis
The version of PHP running on the remote web server is affected by multiple vulnerabilities.Description
According to its banner, the version of PHP running on the remote web server is 7.1.x prior to 7.1.1. It is, therefore, affected by the following vulnerabilities :- A use-after-free error exists that is triggered when handling unserialized object properties. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary code.
(CVE-2016-7479)
- An integer overflow condition exists in the
_zend_hash_init() function in zend_hash.c due to improper validation of unserialized objects. An unauthenticated, remote attacker can exploit this to execute arbitrary code. (CVE-2017-5340)
- A floating pointer exception flaw exists in the exif_convert_any_to_int() function in exif.c that is triggered when handling TIFF and JPEG image tags. An unauthenticated, remote attacker can exploit this to cause a crash, resulting in a denial of service condition. (CVE-2016-10158)
- An out-of-bounds read error exists in the finish_nested_data() function in var_unserializer.c due to improper validation of unserialized data. An unauthenticated, remote attacker can exploit this to cause a crash, resulting in a denial of service condition or the disclosure of memory contents.
(CVE-2016-10161)
- A NULL pointer dereference flaw exists in the php_wddx_pop_element() function in wddx.c due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to cause a crash, resulting in a denial of service condition. (CVE-2016-10162)
- An signed integer overflow condition exists in gd_io.c due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to have an unspecified impact.
- A denial of service vulnerability exists in the bundled GD Graphics Library (LibGD) in the gdImageCreateFromGd2Ctx() function in gd_gd2.c due to improper validation of images. An unauthenticated, remote attacker can exploit this, via a specially crafted image, to crash the process. (CVE-2016-10167)
- An integer overflow condition exists in the gd_io.c script of the GD Graphics Library (libgd). An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-10168)
- An out-of-bounds read error exists in the phar_parse_pharfile() function in phar.c due to improper parsing of phar archives. An unauthenticated, remote attacker can exploit this to cause a crash, resulting in a denial of service condition. (CVE-2017-11147)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
