PHP 5.6.x < 5.6.22 Multiple Vulnerabilities

According to its banner, the version of PHP running on the remote web server is 5.6.x prior to 5.6.22. It is, therefore, affected by multiple vulnerabilities :

• An out-of-bounds read error exists in the _gdContributionsCalc() function within file ext/gd/libgd/gd_interpolation.c. An unauthenticated, remote attacker can exploit this to disclose sensitive information or crash the process linked against the library. (CVE-2013-7456)

• An out-of-bounds read error exists in the get_icu_value_internal() function within file ext/intl/locale/locale_methods.c due to improper handling of user-supplied input. An unauthenticated, remote attacker can exploit this to disclose sensitive information or crash the process linked against the library. (CVE-2016-5093)

• An integer overflow condition exists in the php_html_entities() and php_filter_full_special_chars() functions within file ext/standard/html.c due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to have an unspecified impact. (CVE-2016-5094)

• An integer underflow condition exists in file ext/standard/file.c due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to cause a NULL write, resulting in crashing the process linked against the library. (CVE-2016-5096)

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