"  - An out-of-bounds memory access flaw was found in the
    Linux kernel's system call auditing implementation. On a
    system with existing audit rules defined, a local,
    unprivileged user could use this flaw to leak kernel
    memory to user space or, potentially, crash the system.
    (CVE-2014-3917, Moderate)

This update also fixes the following bugs :

  - A bug in the journaling code (jbd and jbd2) could, under
    very heavy workload of fsync() operations, trigger a
    BUG_ON and result in a kernel oops. Also, fdatasync()
    could fail to immediately write out changes in the file
    size only. These problems have been resolved by
    backporting a series of patches that fixed these
    problems in the respective code on Scientific Linux 6.
    This update also improves performance of ext3 and ext4
    file systems.

  - Due to a bug in the ext4 code, the fdatasync() system
    call did not force the inode size change to be written
    to the disk if it was the only metadata change in the
    file. This could result in the wrong inode size and
    possible data loss if the system terminated
    unexpectedly. The code handling inode updates has been
    fixed and fdatasync() now writes data to the disk as
    expected in this situation.

  - A workaround to a DMA read problem in the tg3 driver was
    incorrectly applied to the whole Broadcom 5719 and 5720
    chipset family. This workaround is valid only to the A0
    revision of the 5719 chips and for other revisions and
    chips causes occasional Tx timeouts. This update
    correctly applies the aforementioned workaround only to
    the A0 revision of the 5719 chips.

  - Due to a bug in the page writeback code, the system
    could become unresponsive when being under memory
    pressure and heavy NFS load. This update fixes the code
    responsible for handling of dirty pages, and dirty page
    write outs no longer flood the work queue.

The system must be rebooted for this update to take effect."
