Ubuntu 10.04 LTS USN-2016-1: Critical Kernel Security Updates on EC2

ubuntu
Calendar Grey November 8, 2013
Scroller Ubuntu
Several security vulnerabilities were patched in Ubuntu's linux-ec2 kernel, mitigating concerns related to information exposure and Denial of Service (DoS) threats.
Several security issues were fixed in the kernel.

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 Interfa...

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.
