QID 671009: EulerOS Security Update for NetworkManager (EulerOS-SA-2021-2665)

NetworkManager is a system service that manages network interfaces and connections based on user or automatic configuration. It supports Ethernet, Bridge, Bond, VLAN, Team, InfiniBand, Wi-Fi, mobile broadband (WWAN), PPPoE and other devices, and supports a variety of different VPN services. Security Fix(es): An exploitable denial of service vulnerability exists in systemd which does not fully implement RFC3203, as it does not support authentication of FORCERENEW packets. A specially crafted DHCP FORCERENEW packet can cause a system, running the DHCP client, to be vulnerable to a DHCP ACK spoofing attack. An attacker can forge a pair of FORCERENEW and DCHPACK packets to reconfigure the system with arbitrary network settings.(CVE-2020-13529)
