USN-3466-1: systemd vulnerability

26 October 2017

systemd could be made to temporarily stop responding if it received specially crafted network traffic.



  • systemd - system and service manager


Karim Hossen & Thomas Imbert and Nelson William Gamazo Sanchez
independently discovered that systemd-resolved incorrectly
handled certain DNS responses. A remote attacker could possibly use this
issue to cause systemd to temporarily stop responding, resulting in a
denial of service.

Update instructions

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

Ubuntu 17.10
Ubuntu 17.04

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