linux vulnerabilities
==========================================================================

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:

A flaw was discovered in the Linux kernel's handling of SCTP handshake. A
remote attacker could exploit this flaw to cause a denial of service
(system crash). (CVE-2014-0101)

An error was discovered in the Linux kernel's DCCP protocol support. A
remote attacked could exploit this flaw to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2014-2523)

Update instructions:

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

Ubuntu 10.04 LTS:
  linux-image-2.6.32-58-386       2.6.32-58.120
  linux-image-2.6.32-58-generic   2.6.32-58.120
  linux-image-2.6.32-58-generic-pae  2.6.32-58.120
  linux-image-2.6.32-58-ia64      2.6.32-58.120
  linux-image-2.6.32-58-lpia      2.6.32-58.120
  linux-image-2.6.32-58-powerpc   2.6.32-58.120
  linux-image-2.6.32-58-powerpc-smp  2.6.32-58.120
  linux-image-2.6.32-58-powerpc64-smp  2.6.32-58.120
  linux-image-2.6.32-58-preempt   2.6.32-58.120
  linux-image-2.6.32-58-server    2.6.32-58.120
  linux-image-2.6.32-58-sparc64   2.6.32-58.120
  linux-image-2.6.32-58-sparc64-smp  2.6.32-58.120
  linux-image-2.6.32-58-versatile  2.6.32-58.120
  linux-image-2.6.32-58-virtual   2.6.32-58.120

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.
