Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS : OpenSSH vulnerabilities (USN-3885-1)

medium Nessus Plugin ID 122055

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3885-1 advisory.

Harry Sintonen discovered multiple issues in the OpenSSH scp utility. If a user or automated system were tricked into connecting to an untrusted server, a remote attacker could possibly use these issues to write to arbitrary files, change directory permissions, and spoof client output.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

Solution

Update the affected packages.
