    value:
"* An integer overflow flaw, leading to a heap-based buffer overflow,
was found in the way the Intel i915 driver in the Linux kernel handled
the allocation of the buffer used for relocation copies. A local user
with console access could use this flaw to cause a denial of service
or escalate their privileges. (CVE-2013-0913, Important)

* A buffer overflow flaw was found in the way UTF-8 characters were
converted to UTF-16 in the utf8s_to_utf16s() function of the Linux
kernel's FAT file system implementation. A local user able to mount a
FAT file system with the 'utf8=1' option could use this flaw to crash
the system or, potentially, to escalate their privileges.
(CVE-2013-1773, Important)

* A flaw was found in the way KVM handled guest time updates when the
buffer the guest registered by writing to the MSR_KVM_SYSTEM_TIME
machine state register (MSR) crossed a page boundary. A privileged
guest user could use this flaw to crash the host or, potentially,
escalate their privileges, allowing them to execute arbitrary code at
the host kernel level. (CVE-2013-1796, Important)

* A potential use-after-free flaw was found in the way KVM handled
guest time updates when the GPA (guest physical address) the guest
registered by writing to the MSR_KVM_SYSTEM_TIME machine state
register (MSR) fell into a movable or removable memory region of the
hosting user-space process (by default, QEMU-KVM) on the host. If that
memory region is deregistered from KVM using
KVM_SET_USER_MEMORY_REGION and the allocated virtual memory reused, a
privileged guest user could potentially use this flaw to escalate
their privileges on the host. (CVE-2013-1797, Important)

* A flaw was found in the way KVM emulated IOAPIC (I/O Advanced
Programmable Interrupt Controller). A missing validation check in the
ioapic_read_indirect() function could allow a privileged guest user to
crash the host, or read a substantial portion of host kernel memory.
(CVE-2013-1798, Important)

* A race condition in install_user_keyrings(), leading to a NULL
pointer dereference, was found in the key management facility. A
local, unprivileged user could use this flaw to cause a denial of
service. (CVE-2013-1792, Moderate)

* A NULL pointer dereference in the XFRM implementation could allow a
local user who has the CAP_NET_ADMIN capability to cause a denial of
service. (CVE-2013-1826, Moderate)

* A NULL pointer dereference in the Datagram Congestion Control
Protocol (DCCP) implementation could allow a local user to cause a
denial of service. (CVE-2013-1827, Moderate)

* Information leak flaws in the XFRM implementation could allow a
local user who has the CAP_NET_ADMIN capability to leak kernel stack
memory to user-space. (CVE-2012-6537, Low)

* Two information leak flaws in the Asynchronous Transfer Mode (ATM)
subsystem could allow a local, unprivileged user to leak kernel stack
memory to user-space. (CVE-2012-6546, Low)

* An information leak was found in the TUN/TAP device driver in the
networking implementation. A local user with access to a TUN/TAP
virtual interface could use this flaw to leak kernel stack memory to
user-space. (CVE-2012-6547, Low)

* An information leak in the Bluetooth implementation could allow a
local user who has the CAP_NET_ADMIN capability to leak kernel stack
memory to user-space. (CVE-2013-0349, Low)

* A use-after-free flaw was found in the tmpfs implementation. A local
user able to mount and unmount a tmpfs file system could use this flaw
to cause a denial of service or, potentially, escalate their
privileges. (CVE-2013-1767, Low)

* A NULL pointer dereference was found in the Linux kernel's USB
Inside Out Edgeport Serial Driver implementation. An attacker with
physical access to a system could use this flaw to cause a denial of
service. (CVE-2013-1774, Low)"
