Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Input validation error

EUVDB-ID: #VU30543

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2014-8179

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

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.

Mitigation

Install update from vendor's website.

Vulnerable software versions

Docker: 1.8.0 - 1.8.2

2) Input validation error

EUVDB-ID: #VU30547

Risk: Low

CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2014-8178

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

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.

Mitigation

Install update from vendor's website.
