1. Summary:

An update for dbus is now available for Red Hat Enterprise Linux 8.

Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AppStream (v. 8) - aarch64, ppc64le, s390x, x86_64

3. Description:

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.

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

For the update to take effect, all running instances of dbus-daemon and all
running applications using the libdbus library must be restarted, or the
system rebooted.

5. Bugs fixed (https://bugzilla.redhat.com/):

2133616 - CVE-2022-42010 dbus: dbus-daemon crashes when receiving message with incorrectly nested parentheses and curly brackets
