Operating system: Linux
PHP version: 5.2.3
PHP Bug Type: Safe Mode/open_basedir
Bug description: open_basedir bypass via glob()
Description:
------------
file_exists() etc. does not allow checking the existence of files outside
the directories specified in open_basedir.
This can be circumvented using glob(). glob() does check open_basedir, but
its return type still reveals whether files exist outside open_basedir. The
existence of a file can be checked using !is_array(glob($filename)).
Reproduce code:
---------------
var_dump(glob('/etc/hosts'));
var_dump(glob('/etc/does-not-exist'));
Expected result:
----------------
bool(false)
bool(false)
or
array(0) {
}
array(0) {
}
Actual result:
--------------
bool(false)
array(0) {
}
