red hat
Calendar Grey January 23, 2023
Dist Redhat Esm H88
Red Hat issued a notable security patch for dbus within Linux 9, targeting various system vulnerabilities and resolutions.
An update for dbus is now available for Red Hat Enterprise Linux 9

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.

Summary

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.
