Debian Security Advisory DSA 202-1 securityat_private
http://www.debian.org/security/ Martin Schulze
December 3rd, 2002 http://www.debian.org/security/faq
- --------------------------------------------------------------------------
Package : im
Vulnerability : temporary files
Problem-Type : local
Debian-specific: no
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.
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).
We recommend that you upgrade your IM package.
wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.
If you are using the apt-get package manager, use the line for
sources.list as given below:
apt-get update
will update the internal database
apt-get upgrade
will install corrected packages
You may use an automated update by adding the resources from the
footer to the proper configuration.
