PHP 4.4.4, 5.1.6, and other versions, when running on Apache, allows local users to modify behavior of other sites hosted on the same web server by modifying the mbstring.func_overload setting within .htaccess, which causes this setting to be applied to other virtual hosts on the same server (CVE-2009-0754). The updated packages have been patched to correct these issues. Affected: 2008.0, 2008.1, 2009.0, Corporate 4.0
