Debian DLA-2041-1 : debian-edu-config security update

high Nessus Plugin ID 132267

Language:

Synopsis

The remote Debian host is missing a security update.

Description

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.

For Debian 8 'Jessie', this problem has been fixed in version 1.818+deb8u3.

We recommend that you upgrade your debian-edu-config packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected debian-edu-config package.
