  script_tag(name:"insight", value:"The kernel packages contain the Linux kernel, the core of any Linux
operating system.

  * A flaw was found in the way the Linux kernel's futex subsystem handled
the requeuing of certain Priority Inheritance (PI) futexes. A local,
unprivileged user could use this flaw to escalate their privileges on the
system. (CVE-2014-3153, Important)

  * A use-after-free flaw was found in the way the ping_init_sock() function
of the Linux kernel handled the group_info reference counter. A local,
unprivileged user could use this flaw to crash the system or, potentially,
escalate their privileges on the system. (CVE-2014-2851, Important)

  * Use-after-free and information leak flaws were found in the way the
Linux kernel's floppy driver processed the FDRAWCMD IOCTL command. A local
user with write access to /dev/fdX could use these flaws to escalate their
privileges on the system. (CVE-2014-1737, CVE-2014-1738, Important)

  * It was found that the aio_read_events_ring() function of the Linux
kernel's Asynchronous I/O (AIO) subsystem did not properly sanitize the AIO
ring head received from user space. A local, unprivileged user could use
this flaw to disclose random parts of the (physical) memory belonging to
the kernel and/or other processes. (CVE-2014-0206, Moderate)

  * An out-of-bounds memory access flaw was found in the Netlink Attribute
extension of the Berkeley Packet Filter (BPF) interpreter functionality in
the Linux kernel's networking implementation. A local, unprivileged user
could use this flaw to crash the system or leak kernel memory to user space
via a specially crafted socket filter. (CVE-2014-3144, CVE-2014-3145,
Moderate)

  * An information leak flaw was found in the way the skb_zerocopy() function
copied socket buffers (skb) that are backed by user-space buffers (for
example vhost-net and Xen netback), potentially allowing an attacker to
read data from those buffers. (CVE-2014-2568, Low)

Red Hat would like to thank Kees Cook of Google for reporting
CVE-2014-3153 and Matthew Daley for reporting CVE-2014-1737 and
CVE-2014-1738. Google acknowledges Pinkie Pie as the original reporter of
CVE-2014-3153. The CVE-2014-0206 issue was discovered by Mateusz Guzik of
Red Hat.

This update also fixes the following bugs:

  * Due to incorrect calculation of Tx statistics in the qlcninc driver,
running the 'ethtool -S ethX' command could trigger memory corruption.
As a consequence, running the sosreport tool, that uses this command,
resulted in a kernel panic. The problem has been fixed by correcting the
said statistics calculation. (BZ#1104972)
