Ubuntu Security Notice 2016-1 - Dan Carpenter discovered an information leak in the HP Smart Aray and Compaq SMART2 disk-array driver in the Linux kernel. A local user could exploit this flaw to obtain sensitive information from kernel memory. Kees Cook discovered flaw in the Human Interface Device (HID) subsystem when CONFIG_HID_ZEROPLUS is enabled. A physically proximate attacker could leverage this flaw to cause a denial of service via a specially crafted device. Various other issues were also addressed.

linux-ec2 vulnerabilities
============================================================================

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

- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux-ec2: Linux kernel for EC2

Details:

Dan Carpenter discovered an information leak in the HP Smart Aray and
Compaq SMART2 disk-array driver in the Linux kernel. A local user could
exploit this flaw to obtain sensitive information from kernel memory.
(CVE-2013-2147)

Kees Cook discovered flaw in the Human Interface Device (HID) subsystem
when CONFIG_HID_ZEROPLUS is enabled. A physically proximate attacker could
leverage this flaw to cause a denial of service via a specially crafted
device. (CVE-2013-2889)

Kees Cook discovered another flaw in the Human Interface Device (HID)
subsystem of the Linux kernel when any of CONFIG_LOGITECH_FF,
CONFIG_LOGIG940_FF, or CONFIG_LOGIWHEELS_FF are enabled. A physcially
proximate attacker can leverage this flaw to cause a denial of service vias
a specially crafted device. (CVE-2013-2893)

Kees Cook discovered yet another flaw in the Human Interface Device (HID)
subsystem of the Linux kernel when CONFIG_HID_MULTITOUCH is enabled. A
physically proximate attacker could leverage this flaw to cause a denial of
service (OOPS) via a specially crafted device. (CVE-2013-2897)

A flaw was discovered in the Linux kernel's dm snapshot facility. A remote
authenticated user could exploit this flaw to obtain sensitive information
or modify/corrupt data. (CVE-2013-4299)

Update instructions:

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

Ubuntu 10.04 LTS:
linux-image-2.6.32-358-ec2 2.6.32-358.71

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.
