Red Hat Security Advisory 2012-1046-01
Posted Jun 28, 2012
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2012-1046-01 - PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server. It was discovered that the PHP XSL extension did not restrict the file writing capability of libxslt. A remote attacker could use this flaw to create or overwrite an arbitrary file that is writable by the user running PHP, if a PHP script processed untrusted eXtensible Style Sheet Language Transformations content. Note: This update disables file writing by default. A new PHP configuration directive, "xsl.security_prefs", can be used to enable file writing in XSLT.
