Important: php security update for Stronghold

Updated PHP packages that fix multiple security issues are now available for
Stronghold 4.0 for Enterprise Linux.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

PHP is an HTML-embedded scripting language commonly used with the Apache
HTTP Web server.

The Hardened-PHP Project discovered an overflow in the PHP htmlentities()
and htmlspecialchars() routines. If a PHP script used the vulnerable
functions to parse UTF-8 data, a remote attacker sending a carefully
crafted request could trigger the overflow and potentially execute
arbitrary code as the 'apache' user. (CVE-2006-5465)

A response-splitting issue was discovered in the PHP session handling. If
a remote attacker can force a carefully crafted session identifier to be
used, a cross-site-scripting or response-splitting attack could be
possible. (CVE-2006-3016)

A buffer overflow was discovered found in the PHP sscanf() function. If a
script used the sscanf() function with positional arguments in the format
string, a remote attacker sending a carefully crafted request could execute
arbitrary code as the 'apache' user. (CVE-2006-4020)

Users of Stronghold should upgrade to these updated packages which contain
backported patches to correct these issues.

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
