v5.0.1

Compare Source

Bugfixes
  • Fixed a bug where rootless containers using the Pasta network driver did not properly handle localhost DNS resolvers on the host leading to DNS resolution issues (#​22044).
  • Fixed a bug where Podman would warn that cgroups v1 systems were no longer supported on FreeBSD hosts.
  • Fixed a bug where HyperV podman machine VMs required an SSH client be installed on the system (#​22075).
  • Fixed a bug that prevented the remote Podman client's podman build command from working properly when connecting from a rootless client to a rootful server (#​22109).
Misc
  • The HyperV driver to podman machine now fails immediately if admin privileges are not available (previously, it would only fail when it reached operations that required admin privileges).

high 7.0: CVE--2023--27561 OWASP Top Ten 2017 Category A9 - Using Components with Known Vulnerabilities

Affected range<=v1.1.4
Fixed versionNot Fixed
CVSS Score7
CVSS VectorCVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
Description

runc through 1.1.4 has Incorrect Access Control leading to Escalation of Privileges, related to libcontainer/rootfs_linux.go. To exploit this, an attacker must be able to spawn two containers with custom volume-mount configurations, and be able to run custom images. NOTE: this issue exists because of a CVE-2019-19921 regression.

medium 6.1: CVE--2023--28642 Improper Preservation of Permissions

Fixed version1.1.5
CVSS Score6.1
CVSS VectorCVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L
Description

Impact

It was found that AppArmor, and potentially SELinux, can be bypassed when /proc inside the container is symlinked with a specific mount configuration.

Patches

Fixed in runc v1.1.5, by prohibiting symlinked /proc: opencontainers/runc#3785

This PR fixes CVE-2023-27561 as well.

Workarounds

Avoid using an untrusted container image.

medium 5.9: CVE--2022--29162 Incorrect Default Permissions

Affected range<1.1.2
Fixed version1.1.2
CVSS Score5.9
CVSS VectorCVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L
Description

Impact

A bug was found in runc where runc exec --cap executed processes with non-empty inheritable Linux process capabilities, creating an atypical Linux environment and enabling programs with inheritable file capabilities to elevate those capabilities to the permitted set during execve(2).

This bug did not affect the container security sandbox as the inheritable set never contained more capabilities than were included in the container's bounding set.

Patches

This bug has been fixed in runc 1.1.2. Users should update to this version as soon as possible.

This fix changes runc exec --cap behavior such that the additional capabilities granted to the process being executed (as specified via --cap arguments) do not include inheritable capabilities.

In addition, runc spec is changed to not set any inheritable capabilities in the created example OCI spec (config.json) file.

low 2.5: CVE--2023--25809 Improper Preservation of Permissions

Affected range<1.1.5
Fixed version1.1.5
CVSS Score2.5
CVSS VectorCVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:N/I:N/A:L
Description

Impact

It was found that rootless runc makes /sys/fs/cgroup writable in following conditons:

  1. when runc is executed inside the user namespace, and the config.json does not specify the cgroup namespace to be unshared (e.g.., (docker|podman|nerdctl) run --cgroupns=host, with Rootless Docker/Podman/nerdctl)
  2. or, when runc is executed outside the user namespace, and /sys is mounted with rbind, ro (e.g., runc spec --rootless; this condition is very rare)

A container may gain the write access to user-owned cgroup hierarchy /sys/fs/cgroup/user.slice/... on the host .
Other users's cgroup hierarchies are not affected.

Patches

v1.1.5 (planned)

Workarounds

  • Condition 1: Unshare the cgroup namespace ((docker|podman|nerdctl) run --cgroupns=private). This is the default behavior of Docker/Podman/nerdctl on cgroup v2 hosts.
  • Condition 2 (very rare): add /sys/fs/cgroup to maskedPaths

Description

Moby is an open source container framework originally developed by Docker Inc. as Docker. It is a key component of Docker Engine, Docker Desktop, and other distributions of container tooling or runtimes. As a batteries-included container runtime, Moby comes with a built-in networking implementation that enables communication between containers, and between containers and external resources.

Moby's networking implementation allows for creating and using many networks, each with their own subnet and gateway. This feature is frequently referred to as custom networks, as each network can have a different driver, set of parameters, and thus behaviors. When creating a network, the --internal flag is used to designate a network as internal. The internal attribute in a docker-compose.yml file may also be used to mark a network internal, and other API clients may specify the internal parameter as well.

When containers with networking are created, they are assigned unique network interfaces and IP addresses (typically from a non-routable RFC 1918 subnet). The root network namespace (hereafter referred to as the 'host') serves as a router for non-internal networks, with a gateway IP that provides SNAT/DNAT to/from container IPs.

Containers on an internal network may communicate between each other, but are precluded from communicating with any networks the host has access to (LAN or WAN) as no default route is configured, and firewall rules are set up to drop all outgoing traffic. Communication with the gateway IP address (and thus appropriately configured host services) is possible, and the host may communicate with any container IP directly.

In addition to configuring the Linux kernel's various networking features to enable container networking, dockerd directly provides some services to container networks. Principal among these is serving as a resolver, enabling service discovery (looking up other containers on the network by name), and resolution of names from an upstream resolver.

When a DNS request for a name that does not correspond to a container is received, the request is forwarded to the configured upstream resolver (by default, the host's configured resolver). This request is made from the container network namespace: the level of access and routing of traffic is the same as if the request was made by the container itself.

As a consequence of this design, containers solely attached to internal network(s) will be unable to resolve names using the upstream resolver, as the container itself is unable to communicate with that nameserver. Only the names of containers also attached to the internal network are able to be resolved.

Many systems will run a local forwarding DNS resolver, typically present on a loopback address (127.0.0.0/8), such as systemd-resolved or dnsmasq. Common loopback address examples include 127.0.0.1 or 127.0.0.53. As the host and any containers have separate loopback devices, a consequence of the design described above is that containers are unable to resolve names from the host's configured resolver, as they cannot reach these addresses on the host loopback device.

To bridge this gap, and to allow containers to properly resolve names even when a local forwarding resolver is used on a loopback address, dockerd will detect this scenario and instead forward DNS requests from the host/root network namespace. The loopback resolver will then forward the requests to its configured upstream resolvers, as expected.

Impact

Because dockerd will forward DNS requests to the host loopback device, bypassing the container network namespace's normal routing semantics entirely, internal networks can unexpectedly forward DNS requests to an external nameserver.

By registering a domain for which they control the authoritative nameservers, an attacker could arrange for a compromised container to exfiltrate data by encoding it in DNS queries that will eventually be answered by their nameservers. For example, if the domain evil.example was registered, the authoritative nameserver(s) for that domain could (eventually and indirectly) receive a request for this-is-a-secret.evil.example.

Docker Desktop is not affected, as Docker Desktop always runs an internal resolver on a RFC 1918 address.

Patches

Moby releases 26.0.0-rc3, 25.0.5 (released) and 23.0.11 (to be released) are patched to prevent forwarding DNS requests from internal networks.

Workarounds

  • Run containers intended to be solely attached to internal networks with a custom upstream address (--dns argument to docker run, or API equivalent), which will force all upstream DNS queries to be resolved from the container network namespace.
