Details

An information leak was discovered in the Linux kernel when inotify is used
to monitor the /dev/ptmx device. A local user could exploit this flaw to
discover keystroke timing and potentially discover sensitive information
like password length. (CVE-2013-0160)

Vasily Kulikov reported a flaw in the Linux kernel's implementation of
ptrace. An unprivileged local user could exploit this flaw to obtain
sensitive information from kernel memory. (CVE-2013-2929)

Andrew Honig reported a flaw in the Linux Kernel's kvm_vm_ioctl_create_vcpu
function of the Kernel Virtual Machine (KVM) subsystem. A local user could
exploit this flaw to gain privileges on the host machine. (CVE-2013-4587)

Andrew Honig reported a flaw in the apic_get_tmcct function of the Kernel
Virtual Machine (KVM) subsystem if the Linux kernel. A guest OS user could
exploit this flaw to cause a denial of service or host OS system crash.
(CVE-2013-6367)

Nico Golde and Fabian Yamaguchi reported a flaw in the driver for Adaptec
AACRAID scsi raid devices in the Linux kernel. A local user could use this
flaw to cause a denial of service or possibly other unspecified impact.
(CVE-2013-6380)

Nico Golde and Fabian Yamaguchi reported buffer underflow errors in the
implementation of the XFS filesystem in the Linux kernel. A local user with
CAP_SYS_ADMIN could exploit these flaw to cause a denial of service (memory
corruption) or possibly other unspecified issues. (CVE-2013-6382)

Evan Huus reported a buffer overflow in the Linux kernel's radiotap header
parsing. A remote attacker could cause a denial of service (buffer over-
read) via a specially crafted header. (CVE-2013-7027)

An information leak was discovered in the recvfrom, recvmmsg, and recvmsg
systemcalls when used with ISDN sockets in the Linux kernel. A local user
could exploit this leak to obtain potentially sensitive information from
kernel memory. (CVE-2013-7266)

An information leak was discovered in the recvfrom, recvmmsg, and recvmsg
systemcalls when used with apple talk sockets in the Linux kernel. A local
user could exploit this leak to obtain potentially sensitive information
from kernel memory. (CVE-2013-7267)

An information leak was discovered in the recvfrom, recvmmsg, and recvmsg
systemcalls when used with ipx protocol sockets in the Linux kernel. A
local user could exploit this leak to obtain potentially sensitive
information from kernel memory. (CVE-2013-7268)

An information leak was discovered in the recvfrom, recvmmsg, and recvmsg
systemcalls when used with the netrom address family in the Linux kernel. A
local user could exploit this leak to obtain potentially sensitive
information from kernel memory. (CVE-2013-7269)

An information leak was discovered in the recvfrom, recvmmsg, and recvmsg
systemcalls when used with packet address family sockets in the Linux
kernel. A local user could exploit this leak to obtain potentially
sensitive information from kernel memory. (CVE-2013-7270)

An information leak was discovered in the recvfrom, recvmmsg, and recvmsg
systemcalls when used with x25 protocol sockets in the Linux kernel. A
local user could exploit this leak to obtain potentially sensitive
information from kernel memory. (CVE-2013-7271)

An information leak was discovered in the Linux kernel's SIOCWANDEV ioctl
call. A local user with the CAP_NET_ADMIN capability could exploit this
flaw to obtain potentially sensitive information from kernel memory.
(CVE-2014-1444)

An information leak was discovered in the wanxl ioctl function the
Linux kernel. A local user could exploit this flaw to obtain potentially
sensitive information from kernel memory. (CVE-2014-1445)

An information leak was discovered in the Linux kernel's hamradio YAM
driver for AX.25 packet radio. A local user with the CAP_NET_ADMIN
capability could exploit this flaw to obtain sensitive information from
kernel memory. (CVE-2014-1446)

Matthew Thode reported a denial of service vulnerability in the Linux
kernel when SELinux support is enabled. A local user with the CAP_MAC_ADMIN
capability (and the SELinux mac_admin permission if running in enforcing
mode) could exploit this flaw to cause a denial of service (kernel crash).
(CVE-2014-1874)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 10.04

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.
