CVE-2019-19921 (GCVE-0-2019-19921)

Vulnerability from cvelistv5 – Published: 2020-02-12 00:00 – Updated: 2024-08-05 02:32

Summary

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.)

Severity ?
