Details

Wolfgang Schweer discovered that Debian-LAN did not properly handle ACLs
for the Kerberos admin server. A local attacker could possibly use this
issue to change the passwords of other users, leading to root privilege
escalation. (CVE-2019-3467)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 18.04

In general, a standard system update will make all the necessary changes.
