Ubuntu 10.04 LTS USN-2128-1 Critical: Kernel Exploits and DoS Threats

ubuntu
Calendar Grey March 6, 2014
Scroller Ubuntu
Multiple security vulnerabilities in the Linux kernel addressed in Ubuntu 10.04 LTS as of March 05, 2014. Significant flaws outlined.
Several security issues were fixed in the kernel.

Summary

Several security issues were fixed in the kernel.

Software Description:

- linux: Linux kernel

Details:

An information leak was discovered in the Linux kernel when inotify is used

to monitor the /dev/ptmx device. A local user could exploit this flaw to

discover keystroke timing and potentially discover sensitive information

like password length. (CVE-2013-0160)

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)

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 den...

Update Instructions

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

Ubuntu 10.04 LTS:
  linux-image-2.6.32-57-386       2.6.32-57.119
  linux-image-2.6.32-57-generic   2.6.32-57.119
  linux-image-2.6.32-57-generic-pae  2.6.32-57.119
  linux-image-2.6.32-57-ia64      2.6.32-57.119
  linux-image-2.6.32-57-lpia      2.6.32-57.119
  linux-image-2.6.32-57-powerpc   2.6.32-57.119
  linux-image-2.6.32-57-powerpc-smp  2.6.32-57.119
  linux-image-2.6.32-57-powerpc64-smp  2.6.32-57.119
  linux-image-2.6.32-57-preempt   2.6.32-57.119
  linux-image-2.6.32-57-server    2.6.32-57.119
  linux-image-2.6.32-57-sparc64   2.6.32-57.119
  linux-image-2.6.32-57-sparc64-smp  2.6.32-57.119
  linux-image-2.6.32-57-versatile  2.6.32-57.119
  linux-image-2.6.32-57-virtual   2.6.32-57.119

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.
