An Insecure Temporary File vulnerability in openSUSE sdbootutil allows local users to pre-create a directory to achieve various effects like:
* gain access to possible private information found in /var/lib/pcrlock.d
* manipulate the data backed up in /tmp/pcrlock.d.bak, therefore violating the integrity of the data should it be restored.
*  overwrite protected system files with data from /var/lib/pcrlock.d by placing symlinks to existing files in the directory tree in /tmp/pcrlock.d.bak.
