The remote Amazon Linux AMI host is missing a security update.
The journal_unmap_buffer function in fs/jbd2/transaction.c in the
Linux kernel before 3.3.1 does not properly handle the _Delay and
_Unwritten buffer head states, which allows local users to cause a
denial of service (system crash) by leveraging the presence of an ext4
filesystem that was mounted with a journal.
