CVE-2024-21626

Status Candidate

Overview

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 namespace, allowing for a container escape by giving access to the host filesystem ("attack 2"). The same attack could be used by a malicious image to allow a container process to gain access to the host filesystem through runc run ("attack 1"). Variants of attacks 1 and 2 could be also be used to overwrite semi-arbitrary host binaries, allowing for complete container escapes ("attack 3a" and "attack 3b"). runc 1.1.12 includes patches for this issue.

runc 1.1.11 File Descriptor Leak Privilege Escalation
Posted Feb 5, 2024
Authored by h00die, Rory McNamara | Site metasploit.com

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.
