CVE-2006-0208 PHP Cross Site Scripting (XSS) flaw
Last modified: 2007-11-30 17:07:22 EST
PHP 5.1.2 has been released:
The release announcement mentions this security fix:
* Possible cross-site scripting problems in certain error conditions.
The problem exists in the way PHP displays error messages. This issue is only
exploitable when 'display_errors' and 'html_errors' are both set to 'On' in the
PHP configuration file. When a HTML error message was being generated, the
output was not properly sanitized, which could allow an attacker to insert
arbitrary HTML, thus allowing a XSS attack.
This issue is only exploitable if 'html_errors' is on, which the configuration
file cleary states should not be used on production machines.
I have verified this flaw exists in the PHP 4.3 and 5.1 branches.
This issue also affects RHEL3 and RHEL2.1
An advisory has been issued which should help the problem
described in this bug report. This report is therefore being
closed with a resolution of ERRATA. For more information
