DESCRIPTION

* CVE-2014-1737, CVE-2014-1738: Local privilege escalation in floppy ioctl.

The floppy driver would leak internal memory addresses to userspace,
and would allow unprivileged userspace code to overwrite those
addresses, allowing for a local privilege escalation and gaining
of root.

* CVE-2014-0196: Pseudo TTY device write buffer handling race.

A race in how the pseudo ttyp (pty) device handled device writes when
two threads/processes wrote to the same pty, the buffer end could be
overwritten. An attacker could use this to cause a denial-of-service or
gain root privileges.
