## 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."
