Description Sam James archtester Gentoo Infrastructure gentoo-dev Security 2021-05-11 08:02:09 UTC
"An exploitable denial-of-service vulnerability exists in Systemd 245. A specially crafted DHCP FORCERENEW packet can cause a server running the DHCP client to be vulnerable to a DHCP ACK spoofing attack. An attacker can forge a pair of FORCERENEW and DCHP ACK packets to reconfigure the server."
