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 that the scanner has not tested for these issues but has instead relied only on the application’s self-reported version number.
