Could a CVE be assigned for this flaw? PHP 5.3.7 changed how the is_a() function worked, and as a result it could allow for remote arbitrary code execution if certain specific conditions are met (the blog post referenced below has a good writeup of the flaw). http://www.byte.nl/blog/2011/09/23/security-bug-in-is_a-function-in-php-5-3-7-5-3-8/ https://bugs.php.net/bug.php?id=55475 https://bugzilla.redhat.com/show_bug.cgi?id=741020 It looks like this is the fix: http://svn.php.net/viewvc/?view=revision&revision=317183 Thanks. --Vincent Danen / Red Hat Security Response Team
