NVD Description

Note: Versions mentioned in the description apply only to the upstream ecryptfs-utils package and not the ecryptfs-utils package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

utils/mount.ecryptfs_private.c in ecryptfs-utils before 90 does not properly check mountpoint permissions, which allows local users to effectively replace any directory with a new filesystem, and consequently gain privileges, via a mount system call.
