GHSA-fh74-hm69-rqjw · 深刻度： medium · エコシステム： go — opencontainers runc contains procfs race condition with a shared volume mount
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.)
