CVE-2017-2623

MEDIUM

rpm-ostree < 2017.3 - Improper Certificate Validation

Title source: llm

Description

It was discovered that rpm-ostree and rpm-ostree-client before 2017.3 fail to properly check GPG signatures on packages when doing layering. Packages with unsigned or badly signed content could fail to be rejected as expected. This issue is partially mitigated on RHEL Atomic Host, where certificate pinning is used by default.
