OpenSSH 5.4 < 7.1p2 Multiple Vulnerabilities

high Nessus Plugin ID 106608
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The SSH server running on the remote host is affected by multiple vulnerabilities.

Description

According to its banner, the version of OpenSSH running on the remote host is 5.x, 6.x or 7.x prior to 7.1p2. It is, therefore, affected by multiple vulnerabilities.

- A potential information disclosure vulnerability which may allow remote servers to obtain sensitive information from process memory by requesting transmission of an entire buffer (CVE-2016-0777)

- A denial of service vulnerability due to a heap-base overflow in roaming_common.c (CVE-2016-07778)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to OpenSSH version 7.1p2 or later.
