Ubuntu 10.04 LTS USN-2129-1 Critical: Linux Kernel EC2 Security Issues

Scroller Ubuntu
The Linux kernel in Ubuntu addressed multiple security flaws, necessitating updates and potential reconfiguration of external modules.
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 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...

Update Instructions

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

Ubuntu 10.04 LTS:
  linux-image-2.6.32-362-ec2      2.6.32-362.75

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.
