Update Bulletin USN-1390-1 highlights multiple kernel vulnerabilities in Ubuntu 8.04 LTS, the updates improve overall system security.
Several security issues were fixed in the kernel.

Summary

Several security issues were fixed in the kernel.

Software Description:

- linux: Linux kernel

Details:

Dan Rosenberg reported errors in the OSS (Open Sound System) MIDI

interface. A local attacker on non-x86 systems might be able to cause a

denial of service. (CVE-2011-1476)

Dan Rosenberg reported errors in the kernel's OSS (Open Sound System)

driver for Yamaha FM synthesizer chips. A local user can exploit this to

cause memory corruption, causing a denial of service or privilege

escalation. (CVE-2011-1477)

Ben Hutchings reported a flaw in the kernel's handling of corrupt LDM

partitions. A local user could exploit this to cause a denial of service or

escalate privileges. (CVE-2011-2182)

A flaw was discovered in the Linux kernel's NFSv4 (Network File System

version 4) file system. A local, unprivileged user could use this flaw to

cause a denial of service by creating a file in a NFSv4 filesystem.

(CVE-2011-4324)

A flaw was found in how the linux kern...

Update Instructions

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

Ubuntu 8.04 LTS:
  linux-image-2.6.24-31-386       2.6.24-31.99
  linux-image-2.6.24-31-generic   2.6.24-31.99
  linux-image-2.6.24-31-hppa32    2.6.24-31.99
  linux-image-2.6.24-31-hppa64    2.6.24-31.99
  linux-image-2.6.24-31-itanium   2.6.24-31.99
  linux-image-2.6.24-31-lpia      2.6.24-31.99
  linux-image-2.6.24-31-lpiacompat  2.6.24-31.99
  linux-image-2.6.24-31-mckinley  2.6.24-31.99
  linux-image-2.6.24-31-openvz    2.6.24-31.99
  linux-image-2.6.24-31-powerpc   2.6.24-31.99
  linux-image-2.6.24-31-powerpc-smp  2.6.24-31.99
  linux-image-2.6.24-31-powerpc64-smp  2.6.24-31.99
  linux-image-2.6.24-31-rt        2.6.24-31.99
  linux-image-2.6.24-31-server    2.6.24-31.99
  linux-image-2.6.24-31-sparc64   2.6.24-31.99
  linux-image-2.6.24-31-sparc64-smp  2.6.24-31.99
  linux-image-2.6.24-31-virtual   2.6.24-31.99
  linux-image-2.6.24-31-xen       2.6.24-31.99

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.
