CVE-2020-1702 : Vulnerability Insights and Analysis
Discover the impact of CVE-2020-1702 affecting containers/image versions before 5.2.0. Learn about the exploit, affected systems, and best practices for mitigation.
This CVE involves a vulnerability in containers/image affecting versions prior to 5.2.0, allowing a malicious container image to consume excessive memory during the container runtime host's image pulling process.
Understanding CVE-2020-1702
This vulnerability can be exploited in Red Hat Enterprise Linux using podman or OpenShift Container Platform, potentially leading to a denial of service attack.
What is CVE-2020-1702?
A flaw in containers/image versions before 5.2.0 allows attackers to crash the image-pulling process by tricking authorized users into pulling a specially crafted container image that consumes unlimited memory.
The Impact of CVE-2020-1702
Exploitation of this vulnerability could result in a denial of service (DoS) condition, leading to service disruption or a complete halt.
Technical Details of CVE-2020-1702
This section provides more in-depth technical insights into the vulnerability.
Vulnerability Description
A malicious container image, when pulled to a container runtime host like Red Hat Enterprise Linux or OpenShift Container Platform, can trigger unbounded memory consumption, potentially crashing the process responsible for pulling the image.
Affected Systems and Versions
- Product: containers/image
- Versions affected: containers-image 5.2.0 and earlier
Exploitation Mechanism
Attackers utilize a specially crafted container image to trigger an unbounded memory consumption scenario during the image pulling process, causing the process to crash.
Mitigation and Prevention
Protective measures and best practices to safeguard systems against CVE-2020-1702.
Immediate Steps to Take
- Avoid pulling container images from untrusted or unknown sources.
- Implement access controls to limit privileges for pulling container images.
Long-Term Security Practices
- Regularly update container runtime hosts and associated software with the latest patches.
- Conduct security audits on container images to detect potential vulnerabilities.
Patching and Updates
Ensure that the containers/image software is updated to version 5.2.0 or higher to mitigate the vulnerability.
