CVE-2022-1227

A privilege escalation flaw was found in Podman. This flaw allows an attacker to publish a malicious image to a public registry. Once this image is downloaded by a potential victim, the vulnerability is triggered after a user runs the 'podman top' command. This action gives the attacker access to the host filesystem, leading to information disclosure or denial of service.

Podman is a tool for managing OCI containers and pods. A privilege escalation flaw was found in Podman. This flaw allows an attacker to publish a malicious image to a public registry. Once this image is downloaded by a potential victim, the vulnerability is triggered after a user runs the 'podman top' command. This action gives the attacker access to the host filesystem, leading to information disclosure or denial of service.

The container-tools module contains tools for working with containers, notably podman, buildah, skopeo, and runc.

Security Fix(es):

• psgo: Privilege escalation in 'podman top' (CVE-2022-1227)

• prometheus/client_golang: Denial of service using InstrumentHandlerCounter (CVE-2022-21698)

• podman: Default inheritable capabilities for linux container should be empty (CVE-2022-27649)

• crun: Default inheritable capabilities for linux container should be empty (CVE-2022-27650)

• buildah: Default inheritable capabilities for linux container should be empty (CVE-2022-27651)

Once this image is downloaded by a potential victim, the vulnerability is triggered after a user runs the 'podman top' command. This action gives the attacker access to the host filesystem, leading to information disclosure or denial of service.

The psgo package executes the 'nsenter' binary, potentially allowing privilege escalation when used in environments where nsenter is provided by an untrusted source.
