CVE-2012-3409 [HIGH] CVE-2012-3409 ecryptfs-utils: suid helper does not restrict mounting filesystems with nosuid,nodev leading to possible privilege escalation
CVE-2012-3409 ecryptfs-utils: suid helper does not restrict mounting filesystems with nosuid,nodev leading to possible privilege escalation
It was reported [1] that the private ecryptfs mount helper (/sbin/mount.ecryptfs_private), which is setuid-root, could allow an unprivileged local user to mount user-controlled ecryptfs shares on the local system. Because the ecryptfs helper does not mount filesystems with the "nosuid" and "nodev" flags, it would be possible for a user to mount a filesystem containing setuid-root binaries and/or device files that could lead to the escalation of their privileges. This could be done via a USB device, if the user had physical access to the system.
It was however also noted [2] that this may only affect version 86 and later, as the encrypted home source
