Ubuntu 12.04 LTS / 14.04 LTS / 15.04 / 15.10 : openssh vulnerabilities (USN-2869-1)

Medium Nessus Plugin ID 87939

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected openssh-client package.
