Security Bulletin

This security bulletin contains one low risk vulnerability.

1) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU78490

Risk: Low

CVSSv4.0: 0.6 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-34969

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to an error in the dbus-daemon when sending a reply message from the "bus driver". If a local privileged user (e.g. root) is using the org.freedesktop.DBus.Monitoring interface to monitor message bus traffic, another unprivileged user with the ability to connect to the same dbus-daemon can force the service to send an unreplyable message and perform a denial of service (DoS) attack.

Mitigation

Update the affected package dbus-1 to the latest version.
