PHP 7.1.x < 7.1.13 Multiple Vulnerabilities

medium Nessus Plugin ID 105773

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 7.1.13. It is, therefore, affected by the following vulnerabilities :

 - A denial of service (DoS) vulnerability exists in the imagecreatefromgif and imagecreatefromstring functions of the gd_gif_in.c script within GD Graphics Library (libgd) due to an integer signedness error. An unauthenticated, remote attacker can exploit this issue, via a crafted GIF file, to cause the applicaiton to stop responding. (CVE-2018-5711)

 - A cross-site scripting (XSS) vulnerability exists due to improper validation of .phar file before returning it to users. An unauthenticated, remote attacker can exploit this, by convincing a user to click a specially crafted URL, to execute arbitrary script code in a user's browser session. (CVE-2018-5712)

 - A denial of service (DoS) vulnerability exists in the ext/standard/http_fopen_wrapper.c script due to http_header_value possibly being a NULL value in an atoi call. An unauthenticated, remote attacker can exploit this issue, via a specifically crafted HTTP response, to cause the application to stop responding. (CVE-2018-14884)

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 7.1.13 or later.
