CVE-2011-1831

Publication date 9 August 2011

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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.
