Security update for Linux kernel (important)

The SUSE Linux Enterprise 11 Service Pack 3 RealTime Extension kernel has
been updated to fix two critical security issues.

The following security bugs have been fixed:

   *

     CVE-2014-1737: The raw_cmd_copyin function in drivers/block/floppy.c

in the Linux kernel through 3.14.3 does not properly handle error
conditions during processing of an FDRAWCMD ioctl call, which allows local
users to trigger kfree operations and gain privileges by leveraging write
access to a /dev/fd device. (bnc#875798)

   *

     CVE-2014-1738: The raw_cmd_copyout function in

drivers/block/floppy.c in the Linux kernel through 3.14.3 does not
properly restrict access to certain pointers during processing of an
FDRAWCMD ioctl call, which allows local users to obtain sensitive
information from kernel heap memory by leveraging write access to a
/dev/fd device. (bnc#875798)

   *

     CVE-2014-0196: The n_tty_write function in drivers/tty/n_tty.c in

the Linux kernel through 3.14.3 does not properly manage tty driver access
in the "LECHO & !OPOST" case, which allows local users to cause a denial
of service (memory corruption and system crash) or gain privileges by
triggering a race condition involving read and write operations with long
strings. (bnc#875690)
