EulerOS Virtualization 2.9.1 : dbus (EulerOS-SA-2023-2954)

medium Nessus Plugin ID 188313

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

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

 - D-Bus before 1.15.6 sometimes allows unprivileged users to crash dbus-daemon. If a privileged user with control over the dbus-daemon is using the org.freedesktop.DBus.Monitoring interface to monitor message bus traffic, then an unprivileged user with the ability to connect to the same dbus-daemon can cause a dbus- daemon crash under some circumstances via an unreplyable message. When done on the well-known system bus, this is a denial-of-service vulnerability. The fixed versions are 1.12.28, 1.14.8, and 1.15.6.
 (CVE-2023-34969)

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 dbus packages.
