Explore the details of Ubuntu Security Notice USN-2354-1, which highlights essential patches addressing kernel vulnerabilities impacting overall system reliability.
Several security issues were fixed in the kernel.

Summary

Several security issues were fixed in the kernel.

Software Description:

- linux: Linux kernel

Details:

Chris Evans reported an flaw in the Linux kernel's handling of iso9660

(compact disk filesystem) images. An attacker who can mount a custom

iso9660 image either via a CD/DVD drive or a loopback mount could cause a

denial of service (system crash or reboot). (CVE-2014-5471)

(compact disk filesystem) images. An attacker who can mount a custom

iso9660 image, with a self-referential CL entry, either via a CD/DVD drive

or a loopback mount could cause a denial of service (unkillable mount

process). (CVE-2014-5472)

Update Instructions

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

Ubuntu 10.04 LTS:
  linux-image-2.6.32-66-386       2.6.32-66.132
  linux-image-2.6.32-66-generic   2.6.32-66.132
  linux-image-2.6.32-66-generic-pae  2.6.32-66.132
  linux-image-2.6.32-66-ia64      2.6.32-66.132
  linux-image-2.6.32-66-lpia      2.6.32-66.132
  linux-image-2.6.32-66-powerpc   2.6.32-66.132
  linux-image-2.6.32-66-powerpc-smp  2.6.32-66.132
  linux-image-2.6.32-66-powerpc64-smp  2.6.32-66.132
  linux-image-2.6.32-66-preempt   2.6.32-66.132
  linux-image-2.6.32-66-server    2.6.32-66.132
  linux-image-2.6.32-66-sparc64   2.6.32-66.132
  linux-image-2.6.32-66-sparc64-smp  2.6.32-66.132
  linux-image-2.6.32-66-versatile  2.6.32-66.132
  linux-image-2.6.32-66-virtual   2.6.32-66.132

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.
