Description
The setup_snappy_os_mounts function in the ubuntu-core-launcher package before 1.0.27.1 improperly determines the mount point of bind mounts when using snaps, which might allow remote attackers to obtain sensitive information or gain privileges via a snap with a name starting with "ubuntu-core."
