---|---|---|---|---|
A flaw was found in Podman. This issue may allow an attacker to create a specially crafted container that, when configured to share the same IPC with at least one other container, can create a large number of IPC resources in /dev/shm. The malicious container will continue to exhaust resources until it is out-of-memory (OOM) killed. While the malicious container's cgroup will be removed, the IPC resources it created are not. Those resources are tied to the IPC namespace that will not be removed until all containers using it are stopped, and one non-malicious container is holding the namespace open. The malicious container is restarted, either automatically or by attacker control, repeating the process and increasing the amount of memory consumed. With a container configured to restart always, such as `podman run --restart=always`, this can result in a memory-based denial of service of the system. | 7.7 |

A vulnerability was found in buildah. Incorrect following of symlinks while reading .containerignore and .dockerignore results in information disclosure. | 5.3 |
Medium |
||
A flaw was found in Buildah. The local path and the lowest subdirectory may be disclosed due to incorrect absolute path traversal, resulting in an impact to confidentiality. | 3.3 |
Low |
||
An incorrect handling of the supplementary groups in the Podman container engine might lead to the sensitive information disclosure or possible data modification if an attacker has direct access to the affected container where supplementary groups are used to set access permissions and is able to execute a binary code in that container. | 7.1 |
