EulerOS Virtualization 3.0.6.0 : systemd (EulerOS-SA-2022-1098)

medium Nessus Plugin ID 157988

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the systemd packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

 - 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 prior to 246.15, 247.8, 248.5, and 249.1 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-2021-33910)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected systemd packages.
