Details

Chris Moberly discovered that snapd versions 2.28 through 2.37 incorrectly
validated and parsed the remote socket address when performing access
controls on its UNIX socket. A local attacker could use this to access
privileged socket APIs and obtain administrator privileges. On Ubuntu
systems with snaps installed, snapd typically will have already
automatically refreshed itself to snapd 2.37.1 which is unaffected.
