Scroller Ubuntu
Multiple vulnerabilities impacting the Linux kernel on EC2 for Ubuntu 10.04 LTS need urgent intervention and patching.
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:

An information leak was discovered in the handling of ICMPv6 Router

Advertisement (RA) messages in the Linux kernel's IPv6 network stack. A

remote attacker could exploit this flaw to cause a denial of service

(excessive retries and address-generation outage), and consequently obtain

sensitive information. (CVE-2013-0343)

Kees Cook discovered flaw in the Human Interface Device (HID) subsystem of

the Linux kernel. A physically proximate attacker could exploit this flaw

to execute arbitrary code or cause a denial of service (heap memory

corruption) via a specially crafted device that provides an invalid Report

ID. (CVE-2013-2888)

Kees Cook discovered a flaw in the Human Interface Device (HID) subsystem

of the Linux kerenl when CONFIG_HID_PANTHERLORD is enabled. A physically

proximate attacker could cause a denial of service (heap out-of-bounds

Update Instructions

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

Ubuntu 10.04 LTS:
  linux-image-2.6.32-357-ec2      2.6.32-357.70

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.
