-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: dbus security update Advisory ID: RHSA-2023:0096-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2023:0096 Issue date: 2023-01-12 CVE Names: CVE-2022-42010 CVE-2022-42011 CVE-2022-42012 ===================================================================== 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 Red Hat Enterprise Linux BaseOS (v. 8) - aarch64, noarch, 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 2133617 - CVE-2022-42011 dbus: dbus-daemon can be crashed by messages with array length inconsistent with element type 2133618 - CVE-2022-42012 dbus: `_dbus_marshal_byteswap` doesn't process fds in messages with "foreign" endianness correctly 6.
