* etc/cron.daily/apport: Only attempt to remove files and symlinks, do not
descend into subdirectories of /var/crash/. Doing so might be exploited by
a race condition between find traversing a huge directory tree, changing
an existing subdir into a symlink to e. g. /etc/, and finally getting that
piped to rm. Patch based on work by Martin Pitt. Thanks to Stephane
