[GLSA]

Gentoo Linux Security Advisory

Title: PHP: Vulnerabilities in included PCRE and XML-RPC libraries (GLSA 200509-19)
Severity: normal
Exploitable: remote
Date: September 27, 2005
Bug(s): #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: dev-php/php
Vulnerable: < 4.4.0-r1
Unaffected: >= 4.3.11-r1 < 4.3.12
Unaffected: >= 4.4.0-r1
Architectures: All supported architectures

Package: dev-php/mod_php
Vulnerable: < 4.4.0-r2
Unaffected: >= 4.3.11-r1 < 4.3.12
Unaffected: >= 4.4.0-r2
Architectures: All supported architectures

Package: dev-php/php-cgi
Vulnerable: < 4.4.0-r2
Unaffected: >= 4.3.11-r2 < 4.3.12
Unaffected: >= 4.4.0-r2
Architectures: All 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:
