EulerOS Virtualization 3.0.2.0 : systemd (EulerOS-SA-2023-1698)

critical Nessus Plugin ID 175214

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 :

 - A use-after-free vulnerability was found in systemd. This issue occurs due to the on_stream_io() function and dns_stream_complete() function in 'resolved-dns-stream.c' not incrementing the reference counting for the DnsStream object. Therefore, other functions and callbacks called can dereference the DNSStream object, causing the use-after-free when the reference is still used later. (CVE-2022-2526)

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.
