Details

A bug has been found in the handling of the open_basedir directive
handling. Contrary to the specification, the value of open_basedir
was handled as a prefix instead of a proper directory name even if it
was terminated by a slash ('/'). For example, this allowed PHP scripts
to access the directory /home/user10 when open_basedir was configured
to '/home/user1/'.
