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.
