Public bug reported:
Binary package hint: cryptsetup
In some situations (I could not yet clearly determine in which exact
conditions this happens), after running cryptsetup, a device /dev/mapper
/temporary-cryptsetup-[0-9]+ (pidnum ?) is left lying around.
Looks like the same as reported in Debian bug #444914
Not sure what this device actually corresponds to or if it might allow
unauthorized access to encrypted content, so I check this as a potential
security vulnerability.
** Affects: cryptsetup (Ubuntu)
