CVE-2024-40635
MEDIUMCVSS Vector
CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:N
Lifecycle Timeline
3Description
containerd is an open-source container runtime. A bug was found in containerd prior to versions 1.6.38, 1.7.27, and 2.0.4 where containers launched with a User set as a `UID:GID` larger than the maximum 32-bit signed integer can cause an overflow condition where the container ultimately runs as root (UID 0). This could cause unexpected behavior for environments that require containers to run as a non-root user. This bug has been fixed in containerd 1.6.38, 1.7.27, and 2.04. As a workaround, ensure that only trusted images are used and that only trusted users have permissions to import images.
Analysis
containerd is an open-source container runtime. Rated medium severity (CVSS 4.6), this vulnerability is low attack complexity. This Integer Overflow vulnerability could allow attackers to cause unexpected behavior through arithmetic overflow.
Technical Context
This vulnerability is classified as Integer Overflow (CWE-190), which allows attackers to cause unexpected behavior through arithmetic overflow. containerd is an open-source container runtime.
