Ubuntu Security Notice USN-2237-1
June 05, 2014

linux-lts-quantal vulnerability
==========================================================================

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

- Ubuntu 12.04 LTS

Summary:

The system could be made to crash or run programs as an administrator.

Software Description:
- linux-lts-quantal: Linux hardware enablement kernel from Quantal

Details:

Pinkie Pie discovered a flaw in the Linux kernel's futex subsystem. An
unprivileged local user could exploit this flaw to cause a denial of
service (system crash) or gain administrative privileges.

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.5.0-51-generic 3.5.0-51.77~precise1

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

Ubuntu Security Notice USN-2238-1
June 05, 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:

Pinkie Pie discovered a flaw in the Linux kernel's futex subsystem. An
unprivileged local user could exploit this flaw to cause a denial of
service (system crash) or gain administrative privileges. (CVE-2014-3153)

A flaw was discovered in the Linux kernel's IPC reference counting. An
unprivileged local user could exploit this flaw to cause a denial of
service (OOM system crash). (CVE-2013-4483)

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.8.0-42-generic 3.8.0-42.62~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.

Ubuntu Security Notice USN-2239-1
June 05, 2014

linux-lts-saucy 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-saucy: Linux hardware enablement kernel from Saucy

Details:

Pinkie Pie discovered a flaw in the Linux kernel's futex subsystem. An
unprivileged local user could exploit this flaw to cause a denial of
service (system crash) or gain administrative privileges. (CVE-2014-3153)

A flaw was discovered in the Linux kernel virtual machine's (kvm)
validation of interrupt requests (irq). A guest OS user could exploit this
flaw to cause a denial of service (host OS crash). (CVE-2014-0155)

An information leak was discovered in the netfilter subsystem of the Linux
kernel. An attacker could exploit this flaw to obtain sensitive information
from kernel memory. (CVE-2014-2568)

Sasha Levin reported a bug in the Linux kernel's virtual memory management
subsystem. An unprivileged local user could exploit this flaw to cause a
denial of service (system crash). (CVE-2014-3122)

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.11.0-23-generic 3.11.0-23.40~precise1
linux-image-3.11.0-23-generic-lpae 3.11.0-23.40~precise1
