Descriptions
In snapd versions prior to 2.62, when using AppArmor for enforcement of
sandbox permissions, snapd failed to restrict writes to the $HOME/bin
path. In Ubuntu, when this path exists, it is automatically added to
the users PATH. An attacker who could convince a user to install a
malicious snap which used the 'home' plug could use this vulnerability
to install arbitrary scripts into the users PATH which may then be run
by the user outside of the expected snap sandbox and hence allow them
to escape confinement.
