Runc Security Vulnerabilities

CVE-2024-21626

runc is a CLI tool for spawning and running containers on Linux according to the OCI specification. In runc 1.1.11 and earlier, due to an internal file descriptor leak, an attacker could cause a newly-spawned container process (from runc exec) to have a working directory in the host filesystem...

CVE-2023-25809

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.....

CVE-2023-28642

runc is a CLI tool for spawning and running containers according to the OCI specification. It was found that AppArmor can be bypassed when /proc inside the container is symlinked with a specific mount configuration. This issue has been fixed in runc version 1.1.5, by prohibiting symlinked /proc....

CVE-2023-27561

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....

CVE-2022-29162

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...

CVE-2022-24769

Moby is an open-source project created by Docker to enable and accelerate software containerization. A bug was found in Moby (Docker Engine) prior to version 20.10.14 where containers were incorrectly started with non-empty inheritable Linux process capabilities, creating an atypical Linux...

CVE-2021-43784

runc is a CLI tool for spawning and running containers on Linux according to the OCI specification. In runc, netlink is used internally as a serialization system for specifying the relevant container configuration to the C portion of the code (responsible for the based namespace setup of...

CVE-2021-30465

runc before 1.0.0-rc95 allows a Container Filesystem Breakout via Directory Traversal. To exploit the vulnerability, an attacker must be able to create multiple containers with a fairly specific mount configuration. The problem occurs via a symlink-exchange attack that relies on a race...

CVE-2019-19921

runc through 1.0.0-rc9 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. (This vulnerability does...

CVE-2019-16884

runc through 1.0.0-rc8, as used in Docker through 19.03.2-ce and other products, allows AppArmor restriction bypass because libcontainer/rootfs_linux.go incorrectly checks mount targets, and thus a malicious Docker image can mount over a /proc...

CVE-2019-5736

runc through 1.0-rc6, as used in Docker before 18.09.2 and other products, allows attackers to overwrite the host runc binary (and consequently obtain host root access) by leveraging the ability to execute a command as root within one of these types of containers: (1) a new container with an...

CVE-2018-11084

Cloud Foundry Garden-runC release, versions prior to 1.16.1, prevents deletion of some app environments based on file attributes. A remote authenticated malicious user may create and delete apps with crafted file attributes to cause a denial of service for new app instances or scaling up of...

CVE-2018-1277

Cloud Foundry Garden-runC, versions prior to 1.13.0, does not correctly enforce disc quotas for Docker image layers. A remote authenticated user may push an app with a malicious Docker image that will consume more space on a Diego cell than allocated in their quota, potentially causing a DoS...

CVE-2018-1191

Cloud Foundry Garden-runC, versions prior to 1.11.0, contains an information exposure vulnerability. A user with access to Garden logs may be able to obtain leaked credentials and perform authenticated actions using those...

CVE-2016-3697

libcontainer/user/user.go in runC before 0.1.0, as used in Docker before 1.11.2, improperly treats a numeric UID as a potential username, which allows local users to gain privileges via a numeric username in the password file in a...
