openssh vulnerabilities

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

- Ubuntu 15.10
- Ubuntu 15.04
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS


OpenSSH could be made to expose sensitive information over the network.

Software Description:
- openssh: secure shell (SSH) for secure access to remote machines


It was discovered that the OpenSSH client experimental support for resuming
connections contained multiple security issues. A malicious server could
use this issue to leak client memory to the server, including private
client user keys.

Update instructions:

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

Ubuntu 15.10:
  openssh-client                  1:6.9p1-2ubuntu0.1

Ubuntu 15.04:
  openssh-client                  1:6.7p1-5ubuntu1.4

Ubuntu 14.04 LTS:
  openssh-client                  1:6.6p1-2ubuntu2.4

Ubuntu 12.04 LTS:
  openssh-client                  1:5.9p1-5ubuntu1.8

In general, a standard system update will make all the necessary changes.
