USN-3466-1: systemd vulnerability
26 October 2017
systemd could be made to temporarily stop responding if it received specially crafted network traffic.
Releases
Packages
- systemd - system and service manager
Details
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.
