Red Hat Security Advisory 2024-0670-03 - An update for runc is now available for Red Hat Enterprise Linux 9.

Debian Linux Security Advisory 5615-1 - It was discovered that runc, a command line client for running applications packaged according to the Open Container Format (OCF), was susceptible to multiple container break-outs due to an internal file descriptor leak.

runc versions 1.1.11 and below, as used by containerization technologies such as Docker engine and Kubernetes, are vulnerable to an arbitrary file write vulnerability. Due to a file descriptor leak it is possible to mount the host file system with the permissions of runc (typically root). Successfully tested on Ubuntu 22.04 with runc 1.1.7-0ubuntu1~22.04.1 using Docker build.

Ubuntu Security Notice 6619-1 - Rory McNamara discovered that runC did not properly manage internal file descriptor while managing containers. An attacker could possibly use this issue to obtain sensitive information or bypass container restrictions.

Multiple security vulnerabilities have been disclosed in the runC command line tool that could be exploited by threat actors to escape the bounds of the container and stage follow-on attacks. The vulnerabilities, tracked as CVE-2024-21626, CVE-2024-23651, CVE-2024-23652, and CVE-2024-23653, have been collectively dubbed Leaky Vessels by cybersecurity vendor Snyk. "These container

Dell Streaming Data Platform prior to 1.4 contains Open Redirect vulnerability. An attacker with privileges same as a legitimate user can phish the legitimate the user to redirect to malicious website leading to information disclosure and launch of phishing attacks.

### 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`: https://github.com/opencontainers/runc/pull/3785 This PR fixes CVE-2023-27561 as well. ### Workarounds Avoid using an untrusted container image.

### 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`

runc is a CLI tool for spawning and running containers according to the OCI specification. In affected versions 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) or 2. 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. Users are advised to upgrade to version 1.1.5. Users unable to upgrade may unshare the cgroup namespace (`(docker|podman|nerdctl) run --cgroupns=private)`. This is the default behavior of Docker/Podman/nerdctl on cgroup v2 hosts. or add `/sys/fs/cgroup` to `m...

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.

### 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. ### Credits The opencontainers project would like to thank [Andrew G. Morgan](https://github.com...

runc is a CLI tool for spawning and running containers on Linux according to the OCI specification. A bug was found in runc prior to version 1.1.2 where `runc exec --cap` created 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.

In Docker before versions 9.03.15, 20.10.3 there is a vulnerability in which pulling an intentionally malformed Docker image manifest crashes the dockerd daemon. Versions 20.10.3 and 19.03.15 contain patches that prevent the daemon from crashing.
