Scroller Ubuntu
Ubuntu 10.04 LTS has rolled out updates addressing critical Linux kernel vulnerabilities, patching CVEs to bolster system security and prevent exploits
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:

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-2.6.32-370-ec2      2.6.32-370.86

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.
