Urgent patch for systemd-resolved in Fedora 25 addressing a buffer overflow flaw. Immediate application of the update is required; system restart is not necessary.
A fix for an out-of-bounds write in systemd-resolved after a crafted DNS packet (CVE-2017-9445)

Summary

systemd is a system and service manager for Linux, compatible with

SysV and LSB init scripts. systemd provides aggressive parallelization

capabilities, uses socket and D-Bus activation for starting services,

offers on-demand starting of daemons, keeps track of processes using

Linux cgroups, supports snapshotting and restoring of the system

state, maintains mount and automount points and implements an

elaborate transactional dependency-based service control logic.

A fix for an out-of-bounds write in systemd-resolved after a crafted DNS packet

(CVE-2017-9445). No need to reboot or log out.
