EulerOS Virtualization 2.11.1 : systemd (EulerOS-SA-2024-2162)

high Nessus Plugin ID 205983

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

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

 Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the 'KeyTrap' issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG records.(CVE-2023-50387)

Tenable has extracted the preceding description block directly from the EulerOS Virtualization systemd security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected systemd packages.
