Severity: Normal Title: PHP: Vulnerabilities in included PCRE and XML-RPC libraries Date: September 27, 2005 Bugs: #102373 ID: 200509-19
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis ========
PHP makes use of an affected PCRE library and ships with an affected XML-RPC library and is therefore potentially vulnerable to remote execution of arbitrary code.
Background ==========
PHP is a general-purpose scripting language widely used to develop web-based applications. It can run inside a web server using the mod_php module or the CGI version of PHP, or can run stand-alone in a CLI.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-php/php < 4.4.0-r1 *>= 4.3.11-r1 >= 4.4.0-r1 2 dev-php/mod_php < 4.4.0-r2 *>= 4.3.11-r1 >= 4.4.0-r2 3 dev-php/php-cgi < 4.4.0-r2 *>= 4.3.11-r2 >= 4.4.0-r2 ------------------------------------------------------------------- 3 affected packages on all of their supported architectures. -------------------------------------------------------------------
Description ===========
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.
Resolution ==========
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
