Additional information
NVDhttps://nvd.nist.gov/vuln/detail/CVE-2016-1572
CWEhttps://cwe.mitre.org/data/definitions/269.html

mount.ecryptfs_private.c in eCryptfs-utils does not validate mount destination filesystem types, which allows local users to gain privileges by mounting over a nonstandard filesystem, as demonstrated by /proc/$pid.

Weakness

The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
