{"id":"CVE-2023-28642","summary":"AppArmor bypass with symlinked /proc in runc","details":"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`. See PR #3785 for details. users are advised to upgrade. Users unable to upgrade should avoid using an untrusted container image.\n\n","aliases":["GHSA-g2j6-57v7-gm8c","GO-2023-1683"],"modified":"2026-03-20T12:27:25.911656Z","published":"2023-03-29T18:15:48.957Z","related":["ALSA-2023:6380","ALSA-2023:6938","ALSA-2023:6939","CGA-rrc4-39xr-5634","MGASA-2023-0125","SUSE-SU-2023:1726-1","SUSE-SU-2023:2003-1","openSUSE-SU-2024:12826-1","openSUSE-SU-2025:15424-1"],"database_specific":{"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/28xxx/CVE-2023-28642.json","cwe_ids":["CWE-281"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/28xxx/CVE-2023-28642.json"},{"type":"ADVISORY","url":"https://github.com/opencontainers/runc/security/advisories/GHSA-g2j6-57v7-gm8c"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-28642"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20241206-0005/"},{"type":"FIX","url":"https://github.com/opencontainers/runc/pull/3785"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/opencontainers/runc","events":[{"introduced":"0"},{"fixed":"f19387a6bec4944c770f7668ab51c4348d9c2f38"}]}],"versions":["v0.0.1","v0.0.2","v0.0.3","v0.0.4","v0.0.5","v0.0.6","v0.0.7","v0.0.8","v0.0.9","v0.1.0","v0.1.1","v1.0.0","v1.0.0-rc1","v1.0.0-rc10","v1.0.0-rc2","v1.0.0-rc3","v1.0.0-rc4","v1.0.0-rc5","v1.0.0-rc6","v1.0.0-rc7","v1.0.0-rc8","v1.0.0-rc9","v1.0.0-rc90","v1.0.0-rc91","v1.0.0-rc92","v1.0.0-rc93","v1.0.0-rc94","v1.0.0-rc95","v1.1.0","v1.1.0-rc.1","v1.1.1","v1.1.2","v1.1.3","v1.1.4"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-28642.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L"}]}
