Amazon Linux 2 : dbus (ALAS-2024-2428)

medium Nessus Plugin ID 189319

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of dbus installed on the remote host is prior to 1.10.24-7. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2428 advisory.

 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)

Tenable has extracted the preceding description block directly from the tested product 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

Run 'yum update dbus' to update your system.
