Ubuntu Security Notice USN-2116-1
February 18, 2014

linux-ti-omap4 vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 13.10

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux-ti-omap4: Linux kernel for OMAP4

Details:

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)

A flaw in the handling of memory regions of the kernel virtual machine
(KVM) subsystem was discovered. A local user with the ability to assign a
device could exploit this flaw to cause a denial of service (memory
consumption). (CVE-2013-4592)

Nico Golde and Fabian Yamaguchi reported a flaw in the Linux kernel's
debugfs filesystem. An administrative local user could exploit this flaw to
cause a denial of service (OOPS). (CVE-2013-6378)

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)

Update instructions:

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

Ubuntu 13.10:
linux-image-3.5.0-238-omap4 3.5.0-238.54

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.

==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux: Linux kernel

Details:

Saran Neti reported a flaw in the ipv6 UDP Fragmentation Offload (UFI) in
the Linux kernel. A remote attacker could exploit this flaw to cause a
denial of service (panic). (CVE-2013-4563)

Mathy Vanhoef discovered an error in the the way the ath9k driver was
handling the BSSID masking. A remote attacker could exploit this error to
discover the original MAC address after a spoofing atack. (CVE-2013-4579)

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)

Andrew Honig reported an error in the Linux Kernel's Kernel Virtual Machine
(KVM) VAPIC synchronization operation. A local user could exploit this flaw
to gain privileges or cause a denial of service (system crash).
(CVE-2013-6368)

Lars Bull discovered a flaw in the recalculate_apic_map function of the
Kernel Virtual Machine (KVM) subsystem in the Linux kernel. A guest OS user
could exploit this flaw to cause a denial of service (host OS crash).
(CVE-2013-6376)

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)

A flaw was discovered in the ipv4 ping_recvmsg function of the Linux
kernel. A local user could exploit this flaw to cause a denial of service
(NULL pointer dereference and system crash). (CVE-2013-6432)

mpd reported an information leak in the recvfrom, recvmmsg, and recvmsg
system calls in the Linux kernel. An unprivileged local user could exploit
this flaw to obtain sensitive information from kernel stack memory.
(CVE-2013-7263)

of the Linux kernel. A local user could exploit this flaw to obtain
sensitive information from kernel stack memory. (CVE-2013-7264)

Ubuntu Security Notice USN-2112-1
February 18, 2014

linux-lts-raring vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux-lts-raring: Linux hardware enablement kernel from Raring

Details:

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)

Dave Jones and Vince Weaver reported a flaw in the Linux kernel's perf
event subsystem that allows normal users to enable function tracing. An
unprivileged local user could exploit this flaw to obtain potentially
sensitive information from the kernel. (CVE-2013-2930)

A flaw in the handling of memory regions of the kernel virtual machine
(KVM) subsystem was discovered. A local user with the ability to assign a
device could exploit this flaw to cause a denial of service (memory
consumption). (CVE-2013-4592)

Nico Golde and Fabian Yamaguchi reported a flaw in the Linux kernel's
debugfs filesystem. An administrative local user could exploit this flaw to
cause a denial of service (OOPS). (CVE-2013-6378)

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.8.0-36-generic 3.8.0-36.52~precise1

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.

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.2.0-59-generic 3.2.0-59.90
linux-image-3.2.0-59-generic-pae 3.2.0-59.90
linux-image-3.2.0-59-highbank 3.2.0-59.90
linux-image-3.2.0-59-omap 3.2.0-59.90
linux-image-3.2.0-59-powerpc-smp 3.2.0-59.90
linux-image-3.2.0-59-powerpc64-smp 3.2.0-59.90
linux-image-3.2.0-59-virtual 3.2.0-59.90

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.

linux-ti-omap4 vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux-ti-omap4: Linux kernel for OMAP4

Details:

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)

Stephan Mueller reported an error in the Linux kernel's ansi cprng random
number generator. This flaw makes it easier for a local attacker to break
cryptographic protections. (CVE-2013-4345)

Andrew Honig reported a flaw in the Linux Kernel's kvm_vm_ioctl_create_vcpu
