Description Prasad J Pandit 2013-03-16 08:39:11 EDT 
Linux kernel built with IOS FS (CONFIG_ISO9660_FS) support is vulnerable to
an information leakage flaw. It occurs when doing an export operation via
routine - isofs_export_encode_fh - reachable from - name_to_handle_at - syscall.

A user/program could use this flaw to leak kernel memory bytes.
