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