RHEL 8 : dbus (RHSA-2023:0096)

medium Nessus Plugin ID 169967

Synopsis

The remote Red Hat host is missing one or more security updates for dbus.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:0096 advisory.

D-Bus is a system for sending messages between applications. It is used both for the system-wide message bus service, and as a per-user-login-session messaging facility.

Security Fix(es):

* dbus: dbus-daemon crashes when receiving message with incorrectly nested parentheses and curly brackets (CVE-2022-42010)

* dbus: dbus-daemon can be crashed by messages with array length inconsistent with element type (CVE-2022-42011)

* dbus: `_dbus_marshal_byteswap` doesn't process fds in messages with foreign endianness correctly (CVE-2022-42012)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL dbus package based on the guidance in RHSA-2023:0096.
