CVE detail
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 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.

Exploitpacketstormsecurity.comJan 31, 2024, 10:15 PM Security researchers have found four vulnerabilities in Docker components that could allow attackers to access host operating systems from within containers. One of those vulnerabilities is in runc, a command-line tool for spawning and running containers on Linux that underpins multiple container engines, not just Docker. The vulnerabilities were found by Rory McNamara, a researcher […]
