+Subject: [PATCH] cadence_aloop_daemon: place lockfile into non-public
+ directory
+
+The fixed /tmp path for the lock / shutdown handling of the daemon is
+problematic security wise, since any other user in the system can block
+this path. This also makes parallel instances for multiple user accounts
+impossible.
+
+Select a location in the user's /run directory or in its home directory
+(as a fallback).

+Subject: [PATCH] cadence.py: wine ASIO settings: use safe tempfile
+
+This fixed tempfile path poses a security issue that even might allow
+other users on the system to inject arbitrary wine registry settings, if
+protect_symlinks and protect_regular kernel protection is not enabled.
+
+Use a proper NamedTemporaryFile to pass the data to regedit to fix this.
