Detail

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

Summary:

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

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

Details:

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:
