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 …
What kind of vulnerability is it? Who is impacted? Users running containers with root privileges allowing a container to run with read/write access to the host system files when selinux is not enabled. With selinux enabled, some read access is allowed.
A Time-of-check Time-of-use (TOCTOU) flaw was found in podman. This issue may allow a malicious user to replace a normal file in a volume with a symlink while exporting the volume, allowing for access to arbitrary files on the host file system.
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.
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.
A vulnerability was found in buildah. Incorrect following of symlinks while reading .containerignore and .dockerignore results in information disclosure.
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.
A path traversal vulnerability has been discovered in podman before version 1.4.0 in the way it handles symlinks inside containers. An attacker who has compromised an existing container can cause arbitrary files on the host filesystem to be read/written when an administrator tries to copy a file from/to the container.
An issue was discovered in Podman in libpod before 1.6.0. It resolves a symlink in the host context during a copy operation from the container to the host, because an undesired glob operation occurs. An attacker could create a container image containing particular symlinks that, when copied by a victim user to the host filesystem, may overwrite existing files with others from the host.
It has been discovered that podman before version 0.6.1 does not drop capabilities when executing a container as a non-root user. This results in unnecessary privileges being granted to the container.
A flaw was found in Podman, where containers were started incorrectly with non-empty default permissions. A vulnerability was found in Moby (Docker Engine), where containers were started incorrectly with non-empty inheritable Linux process capabilities. This flaw allows an attacker with access to programs with inheritable file capabilities to elevate those capabilities to the permitted set when execve(2) runs.
