CVE-2024-2307
Description
A flaw was found in osbuild-composer. A condition can be triggered that disables GPG verification for package repositories, which can expose the build phase to a Man-in-the-Middle attack, allowing untrusted code to be installed into an image being built.
Statement
The race condition in osbuild-composer that leads to unintentional GPG verification disabling for third-party repositories introduces a moderate severity risk. While the issue can potentially allow the installation of untrusted code into built images, its impact is limited to scenarios where both a third-party repository with GPG-checked RPMs and another repository with GPG checking disabled are concurrently added. Additionally, the insecure setting winning due to the race condition further narrows the circumstances under which the vulnerability can be exploited. However, the potential for bypassing GPG verification in specific configurations poses a tangible risk to the integrity of built images, justifying its classification as a moderate severity issue.
Mitigation
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
