SB2019121721 - Multiple vulnerabilities in Docker Docker

Description

This security bulletin contains information about 2 vulnerabilities.

1) Input validation error (CVE-ID: CVE-2014-8179)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N]

The vulnerability allows a remote non-authenticated attacker to manipulate data.

Docker Engine before 1.8.3 and CS Docker Engine before 1.6.2-CS7 does not properly validate and extract the manifest object from its JSON representation during a pull, which allows attackers to inject new attributes in a JSON object and bypass pull-by-digest validation.

2) Input validation error (CVE-ID: CVE-2014-8178)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 6.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N]

The vulnerability allows a local non-authenticated attacker to manipulate data.

Docker Engine before 1.8.3 and CS Docker Engine before 1.6.2-CS7 do not use a globally unique identifier to store image layers, which makes it easier for attackers to poison the image cache via a crafted image in pull or push commands.

Remediation

Install update from vendor's website.
