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

Solution

Upgrade to PHP version 5.6.22 or later.
