Tatsuya Kinoshita discovered that IM, which contains interface commands and Perl libraries for E-mail and NetNews, creates temporary files insecurely.
These problems have been fixed in version 141-18.1 for the current stable distribution (woody), in version 133-2.2 of the old stable distribution (potato) and in version 141-20 for the unstable distribution (sid).

"Tatsuya Kinoshita discovered that IM, which contains interface
commands and Perl libraries for E-mail and NetNews, creates temporary
files insecurely.
- The impwagent program creates a temporary directory in
an insecure manner in /tmp using predictable directory
names without checking the return code of mkdir, so it's
possible to seize a permission of the temporary
directory by local access as another user.
- The immknmz program creates a temporary file in an
insecure manner in /tmp using a predictable filename, so
an attacker with local access can easily create and
overwrite files as another user.
These problems have been fixed in version 141-18.1 for the current
stable distribution (woody), in version 133-2.2 of the old stable
distribution (potato) and in version 141-20 for the unstable
