Summary

The remote host is missing an update for the 'debian-edu-config' package(s) announced via the DSA-2041-1 advisory.

Insight

Insight

It was discovered that debian-edu-config, the package containing the configuration files and scripts for Debian Edu (Skolelinux), contained an insecure configuration for kadmin, the Kerberos administration server. The insecure configuration allowed every user to change other users' passwords, thus impersonating them and possibly gaining their privileges. The bug was not exposed in the officially documented user management frontends of Debian Edu, but could be abused by local network users knowing how to use the Kerberos backend.
