Debian: New noweb packages fix insecure temporary file creation

Jakob Lell discovered a bug in the 'noroff' script included in noweb whereby a temporary file was created insecurely. During a review, several other instances of this problem were found and fixed. Any of these bugs could be exploited by a local user to overwrite arbitrary files owned by the user invoking the script. Fixed packages are available from security.debian.org.

Jakob Lell discovered a bug in the 'noroff' script included in noweb

several other instances of this problem were found and fixed.  Any of
