EulerOS Virtualization for ARM 64 3.0.5.0 : systemd (EulerOS-SA-2020-1054)

medium Nessus Plugin ID 132808

Synopsis

The remote EulerOS Virtualization for ARM 64 host is missing a security update.

Description

According to the version of the systemd packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerability :

 - In systemd 240, bus_open_system_watch_bind_with_description in shared/bus-util.c (as used by systemd-resolved to connect to the system D-Bus instance), calls sd_bus_set_trusted, which disables access controls for incoming D-Bus messages. An unprivileged user can exploit this by executing D-Bus methods that should be restricted to privileged users, in order to change the system's DNS resolver settings.(CVE-2019-15718)

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 package.
