Dist Ubuntu Esm H88
Follow these crucial steps to resolve kernel issues on Ubuntu 10.04 LTS, enhancing security via linux-ec2 updates to mitigate vulnerabilities.
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:

Don Bailey discovered a flaw in the LZO decompress algorithm used by the

Linux kernel. An attacker could exploit this flaw to cause a denial of

service (memory corruption or OOPS). (CVE-2014-4608)

Andy Lutomirski discovered that the Linux kernel was not checking the

CAP_SYS_ADMIN when remounting filesystems to read-only. A local user could

exploit this flaw to cause a denial of service (loss of writability).

(CVE-2014-7975)

Update Instructions

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

Ubuntu 10.04 LTS:
  linux-image-2.6.32-372-ec2      2.6.32-372.89

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.
