CVE-2023-25173
Description
A flaw was found in containerd, where supplementary groups are not set up properly inside a container. If an attacker has direct access to a container and manipulates their supplementary group access, they may be able to use supplementary group access to bypass primary group restrictions in some cases. This issue can allow access to sensitive information or gain the ability to execute code in that container.
