CVE-2015-8747
The (not configured by default and not available on Wheezy)
multifilesystem storage backend allows read and write access to
arbitrary files (still subject to the DAC permissions of the user
the radicale server is running as).

CVE-2015-8748
If an attacker is able to authenticate with a user name like `.*',
he can bypass read/write limitations imposed by regex-based rules,
including the built-in rules `owner_write' (read for everybody,
write for the calendar owner) and `owner_only' (read and write for
the the calendar owner).");
