The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:8977 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)
dbus: _dbus_marshal_byteswap
doesn’t process fds in messages with foreign endianness correctly (CVE-2022-42012)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
