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. For Debian 8 "Jessie", this problem has been fixed in version 1.818+deb8u3. We recommend that you upgrade your debian-edu-config packages.
