OCI image importer memory exhaustion in github.com/containerd/containerd

Moderate severity GitHub Reviewed Published Feb 16, 2023 in containerd/containerd • Updated Sep 6, 2024

Package

gomod github.com/containerd/containerd (Go)

Affected versions

>= 1.6.0, < 1.6.18
< 1.5.18

Patched versions

1.6.18
1.5.18

Description

Impact

When importing an OCI image, there was no limit on the number of bytes read for certain files. A maliciously crafted image with a large file where a limit was not applied could cause a denial of service.

Patches

This bug has been fixed in containerd 1.6.18 and 1.5.18. Users should update to these versions to resolve the issue.

Workarounds

Ensure that only trusted images are used and that only trusted users have permissions to import images.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
