Red Hat OpenShift Container Platform 3.11 update for kubernetes

1) Inclusion of Sensitive Information in Log Files

EUVDB-ID: #VU48977

Risk: Low

CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2020-8564

CWE-ID: CWE-532 - Information Exposure Through Log Files

Exploit availability: No

Description

The vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to software stores sensitive information into log files. In Kubernetes clusters using a logging level of at least 4, processing a malformed docker config file will result in the contents of the docker config file being leaked, which can include pull secrets or other registry credentials. A local user can read the log files and gain access to sensitive data.

Mitigation

Install updates from vendor's website.
