Summary
Updated systemd packages fix security vulnerabilities
Details

This systemd update provides the v246.15 maintenance release and fixes at least the following security issues:

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 (CVE-2020-13529).

basic/unit-name.c in systemd 220 through 248 has a Memory Allocation with an Excessive Size Value (involving strdupa and alloca for a pathname controlled by a local attacker) that results in an operating system crash (CVE-2021-29270).
