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.

 - 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)
