How to fix?

Upgrade AlmaLinux:8 container-tools:1.0/oci-umount to version 2:2.3.4-2.git87f9237.module_el8.4.0+2496+12421f43 or higher.
This issue was patched in ALSA-2019:4269.

NVD Description

Note: Versions mentioned in the description apply only to the upstream container-tools:1.0/oci-umount package and not the container-tools:1.0/oci-umount package as distributed by AlmaLinux. See How to fix? for AlmaLinux:8 relevant fixed versions and status.

runc through 1.0.0-rc8, as used in Docker through 19.03.2-ce and other products, allows AppArmor restriction bypass because libcontainer/rootfs_linux.go incorrectly checks mount targets, and thus a malicious Docker image can mount over a /proc directory.
