| CVE-2019-5736 | Hig | 0.60 | 8.6 | 0.98 | Feb 11, 2019 | 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… | ||
| CVE-2024-21626 | Hig | 0.53 | 8.6 | 0.18 | Jan 31, 2024 | 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… | ||
| CVE-2021-30465 | Hig | 0.49 | 8.5 | 0.07 | May 27, 2021 | 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… | ||
