    value:
"* A buffer overflow flaw was found in the way the qeth_snmp_command()
function in the Linux kernel's QETH network device driver
implementation handled SNMP IOCTL requests with an out-of-bounds
length. A local, unprivileged user could use this flaw to crash the
system or, potentially, escalate their privileges on the system.
(CVE-2013-6381, Important)

* A flaw was found in the way the ipc_rcu_putref() function in the
Linux kernel's IPC implementation handled reference counter
decrementing. A local, unprivileged user could use this flaw to
trigger an Out of Memory (OOM) condition and, potentially, crash the
system. (CVE-2013-4483, Moderate)

* It was found that the Xen hypervisor implementation did not
correctly check privileges of hypercall attempts made by HVM guests,
allowing hypercalls to be invoked from protection rings 1 and 2 in
addition to ring 0. A local attacker in an HVM guest able to execute
code on privilege levels 1 and 2 could potentially use this flaw to
further escalate their privileges in that guest. Note: Xen HVM guests
running unmodified versions of Scientific Linux and Microsoft Windows
are not affected by this issue because they are known to only use
protection rings 0 (kernel) and 3 (userspace). (CVE-2013-4554,
Moderate)

* A flaw was found in the way the Linux kernel's Adaptec RAID
controller (aacraid) checked permissions of compat IOCTLs. A local
attacker could use this flaw to bypass intended security restrictions.
(CVE-2013-6383, Moderate)

A privileged user in a guest running under the Xen hypervisor could
use this flaw to cause a denial of service on the host system. This
update adds a workaround to the Xen hypervisor implementation, which
mitigates the AMD CPU issue. Note: this issue only affects AMD Family
16h Models 00h-0Fh Processors. Non-AMD CPUs are not vulnerable.
(CVE-2013-6885, Moderate)

* It was found that certain protocol handlers in the Linux kernel's
networking implementation could set the addr_len value without
initializing the associated data structure. A local, unprivileged user
could use this flaw to leak kernel stack memory to user space using
the recvmsg, recvfrom, and recvmmsg system calls. (CVE-2013-7263, Low)

* A flaw was found in the way the get_dumpable() function return value
was interpreted in the ptrace subsystem of the Linux kernel. When
'fs.suid_dumpable' was set to 2, a local, unprivileged local user
could use this flaw to bypass intended ptrace restrictions and obtain
potentially sensitive information. (CVE-2013-2929, Low)

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