Scroller Ubuntu
Several kernel flaws addressed in Ubuntu 10.04 LTS to mitigate denial of service and restrict privilege escalation threats.
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:

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...

Update Instructions

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

Ubuntu 10.04 LTS:
  linux-image-2.6.32-365-ec2      2.6.32-365.79

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.
