Ubuntu 16.04 LTS / 18.04 LTS / 18.10 / 19.04 : Docker vulnerabilities (USN-4048-1)

high Nessus Plugin ID 126564
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 remote Ubuntu host is missing a security-related patch.

Description

Aleksa Sarai discovered that Docker was vulnerable to a directory traversal attack. An attacker could use this vulnerability to read and write arbitrary files on the host filesystem as root.

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 docker.io package.
