tag_insight = "Despite popular belief, the IM packages are not architecture
independent, since the number of the fsync syscal is detected on
build time and this number differs on Linux architectures and
other operating systems.  As a result of this the optional feature
``NoSync=no'' does only work on the architecture the package was
built on.  As usual, we are including the text of the original
advisory DSA 202-1:

Tatsuya Kinoshita discovered that IM, which contains interface
commands and Perl libraries for E-mail and NetNews, creates
temporary files insecurely.

1. 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.

2. 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.

This problem has been fixed in version 141-18.2 for the current
stable distribution (woody), in version 133-2.3 of the old stable
distribution (potato).  A correection is expected for the unstable
distribution (sid) soon.

We recommend that you upgrade your IM package.";
