CVE-2023-25153: Linuxfoundation Containerd

Medium severity, CVSS 5.5. EPSS: 0.4% chance of exploitation in the next 30 days.

containerd is an open source container runtime. Before versions 1.6.18 and 1.5.18, 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. This bug has been fixed in containerd 1.6.18 and 1.5.18. Users should update to these versions to resolve the issue. As a workaround, ensure that only trusted images are used and that only trusted users have permissions to import images.

Affected products

• Linuxfoundation Containerd: before 1.5.18 (fixed in 1.5.18); from 1.6.0, before 1.6.18 (fixed in 1.6.18)
