Detailed Description According to its banner, the version of PHP running on the remote web server is 7.0.x prior to 7.0.6. It is, therefore, affected by multiple vulnerabilities :

- A signedness error exists in the GD Graphics library within file gd_gd2.c due to improper validation of user-supplied input when handling compressed GD2 data. An unauthenticated, remote attacker can exploit this to cause a heap-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2016-3074)

- An integer overflow condition exists in ZipArchive in the getFromIndex() and getFromName() functions due to improper validation of user-supplied input when handling specially crafted ZIP files. An unauthenticated, remote attacker can exploit this to cause a heap-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2016-3078)

- An out-of-bounds read error exists within file ext/intl/grapheme/grapheme_string.c when handling negative offsets in the zif_grapheme_stripos() function. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or disclose memory contents.

- An out-of-bounds read error exists in the php_str2num() function within file ext/bcmath/bcmath.c when handling negative scales. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the disclosure of memory contents.

- An out-of-bounds read error exists in the exif_read_data() function within file ext/exif/exif.c when handling exif headers. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the disclosure of memory contents.

- A flaw exists in the xml_parse_into_struct() function within file ext/xml/xml.c when handling specially crafted XML contents. An unauthenticated, remote attacker can exploit this to cause a denial of service condition.

* Note: This check solely relied on the version number of the remote PHP to assess this vulnerability, so this might be a false positive.
