high Nessus Plugin ID 19818
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200509-19 (PHP: Vulnerabilities in included PCRE and XML-RPC libraries)

PHP makes use of a private copy of libpcre which is subject to an integer overflow leading to a heap overflow (see GLSA 200508-17). It also ships with an XML-RPC library affected by a script injection vulnerability (see GLSA 200508-13).
Impact :

An attacker could target a PHP-based web application that would use untrusted data as regular expressions, potentially resulting in the execution of arbitrary code. If web applications make use of the XML-RPC library shipped with PHP, they are also vulnerable to remote execution of arbitrary PHP code.
Workaround :

There is no known workaround at this time.

Solution

All PHP users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose dev-php/php All mod_php users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose dev-php/mod_php All php-cgi users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose dev-php/php-cgi
