fedora
Calendar Grey February 12, 2019
Dist Fedora Esm H88
Resolve memory management flaw in radvd within Fedora 28, improving the security posture of the IPv6 daemon through essential patches.
Fix double-free in InterfaceList ---- Depends on network-online target (#1652459)

Summary

radvd is the router advertisement daemon for IPv6. It listens to router

solicitations and sends router advertisements as described in "Neighbor

Discovery for IP Version 6 (IPv6)" (RFC 2461). With these advertisements

hosts can automatically configure their addresses and some other

parameters. They also can choose a default router based on these

advertisements.

Install radvd if you are setting up IPv6 network and/or Mobile IPv6

services.
