Affected: DNS- and DHCP server und
Impact: Brief unavailability of the DNS and DHCP service

Dear GÖNET participants,

another exceedingly urgent security update for the DNS resolver and DHCP server are necessary:

Here, the DNS as well as the DHCP service on the servers restarts, which may cause an interruption of several seconds.

The updates of the two servers will be performed in succession, so that one of both servers will always be available
