All reports of possibly-insecure-handling-of-tmp-files-in-maintainer-script for the archive. The extended description of this tag is:
The maintainer script seems to access a file in /tmp or some other temporary directory. Since creating temporary files in a world-writable directory is very dangerous, this is likely to be a security bug. Use the tempfile or mktemp utilities to create temporary files in these directories.
Refer to Debian Policy Manual section 10.4 (Scripts) for details.
