[GLSA-200509-19] PHP: Vulnerabilities in included PCRE and XML-RPC libraries

Vulnerability Assessment Summary
PHP: Vulnerabilities in included PCRE and XML-RPC libraries

Detailed Explanation for this Vulnerability Assessment
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

A possible hacker 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.
