{"id":"ALPINE-CVE-2019-19921","details":"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 not affect Docker due to an implementation detail that happens to block the attack.)","modified":"2026-11-03T06:31:56.569820470Z","published":"2020-02-12T15:15:12.210Z","upstream":["CVE-2019-19921"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2019-19921"}],"affected":[{"package":{"name":"containerd","ecosystem":"Alpine:v3.11","purl":"pkg:apk/alpine/containerd?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.3.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-19921.json"}},{"package":{"name":"containerd","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/containerd?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.3.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-19921.json"}},{"package":{"name":"containerd","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/containerd?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.3.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-19921.json"}},{"package":{"name":"containerd","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/containerd?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.3.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-19921.json"}},{"package":{"name":"containerd","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/containerd?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.3.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-19921.json"}},{"package":{"name":"containerd","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/containerd?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.3.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-19921.json"}},{"package":{"name":"containerd","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/containerd?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.3.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-19921.json"}},{"package":{"name":"containerd","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/containerd?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.3.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-19921.json"}},{"package":{"name":"containerd","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/containerd?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.3.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-19921.json"}},{"package":{"name":"containerd","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/containerd?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.3.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-19921.json"}},{"package":{"name":"containerd","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/containerd?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.3.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-19921.json"}},{"package":{"name":"containerd","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/containerd?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.3.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-19921.json"}},{"package":{"name":"containerd","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/containerd?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.3.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-19921.json"}},{"package":{"name":"containerd","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/containerd?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.3.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-19921.json"}},{"package":{"name":"runc","ecosystem":"Alpine:v3.11","purl":"pkg:apk/alpine/runc?arch=source"},"ranges":[{"type":"ECOSYST
