Ubuntu Security Notice 2233-1 - Pinkie Pie discovered a flaw in the Linux kernel's futex subsystem. An unprivileged local user could exploit this flaw to cause a denial of service (system crash) or gain administrative privileges. Dmitry Vyukov reported a flaw in the Linux kernel's handling of IPv6 UDP Fragmentation Offload (UFO) processing. A remote attacker could leverage this flaw to cause a denial of service (system crash). Hannes Frederic Sowa discovered a flaw in the Linux kernel's UDP Fragmentation Offload (UFO). An unprivileged local user could exploit this flaw to cause a denial of service (system crash) or possibly gain administrative privileges. Various other issues were also addressed.

============================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux: Linux kernel

Details:

Pinkie Pie discovered a flaw in the Linux kernel's futex subsystem. An
unprivileged local user could exploit this flaw to cause a denial of
service (system crash) or gain administrative privileges. (CVE-2014-3153)

Dmitry Vyukov reported a flaw in the Linux kernel's handling of IPv6 UDP
Fragmentation Offload (UFO) processing. A remote attacker could leverage
this flaw to cause a denial of service (system crash). (CVE-2013-4387)

Hannes Frederic Sowa discovered a flaw in the Linux kernel's UDP
Fragmentation Offload (UFO). An unprivileged local user could exploit this
flaw to cause a denial of service (system crash) or possibly gain
administrative privileges. (CVE-2013-4470)

A flaw was discovered in the Linux kernel's IPC reference counting. An
unprivileged local user could exploit this flaw to cause a denial of
service (OOM system crash). (CVE-2013-4483)

halfdog reported an error in the AMD K7 and K8 platform support in the
Linux kernel. An unprivileged local user could exploit this flaw on AMD
based systems to cause a denial of service (task kill) or possibly gain
privileges via a crafted application. (CVE-2014-1438)

Sasha Levin reported a bug in the Linux kernel's virtual memory management
subsystem. An unprivileged local user could exploit this flaw to cause a
denial of service (system crash). (CVE-2014-3122)

Update instructions:

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

Ubuntu 10.04 LTS:
linux-image-2.6.32-61-386 2.6.32-61.124
linux-image-2.6.32-61-generic 2.6.32-61.124
linux-image-2.6.32-61-generic-pae 2.6.32-61.124
linux-image-2.6.32-61-ia64 2.6.32-61.124
linux-image-2.6.32-61-lpia 2.6.32-61.124
linux-image-2.6.32-61-powerpc 2.6.32-61.124
linux-image-2.6.32-61-powerpc-smp 2.6.32-61.124
linux-image-2.6.32-61-powerpc64-smp 2.6.32-61.124
linux-image-2.6.32-61-preempt 2.6.32-61.124
linux-image-2.6.32-61-server 2.6.32-61.124
linux-image-2.6.32-61-sparc64 2.6.32-61.124
linux-image-2.6.32-61-sparc64-smp 2.6.32-61.124
linux-image-2.6.32-61-versatile 2.6.32-61.124
linux-image-2.6.32-61-virtual 2.6.32-61.124

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.
