========================================================================== Ubuntu Security Notice USN-4960-1 May 19, 2021
runc vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 21.04 - Ubuntu 20.10 - Ubuntu 20.04 LTS - Ubuntu 18.04 LTS
Summary:
runC could be made to overwrite files as the administrator.
Software Description: - runc: Open Container Project
Details:
Etienne Champetier discovered that runC incorrectly checked mount targets. An attacker with a malicious container image could possibly mount the host filesystem into the container and escalate privileges.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 21.04: runc 1.0.0~rc93-0ubuntu1.1
Ubuntu 20.10: runc 1.0.0~rc93-0ubuntu1~20.10.2
Ubuntu 20.04 LTS: runc 1.0.0~rc93-0ubuntu1~20.04.2
Ubuntu 18.04 LTS: runc 1.0.0~rc93-0ubuntu1~18.04.2
In general, a standard system update will make all the necessary changes.
