Comment 1 Tomas Hoger 2011-01-19 12:40:01 EST

This is under the full control of the script author, hence may possibly allow safe_mode / open_basedir restrictions.

*** This bug has been marked as a duplicate of bug 169857 ***

Comment 2 Tomas Hoger 2011-01-20 06:17:52 EST

Statement:

We do not consider safe_mode / open_basedir restriction bypass issues to be security sensitive.  For more details see http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=169857#c1 and http://www.php.net/security-note.php
