Vulnerability from csaf_redhat - Published: 2022-09-20 13:41 - Updated: 2024-11-22 20:00Summary
Red Hat Security Advisory: dbus-broker security update
Notes
Topic
An update for dbus-broker is now available for Red Hat Enterprise Linux 9.
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.
Details
dbus-broker is an implementation of a message bus as defined by the D-Bus specification. Its aim is to provide high performance and reliability, while keeping compatibility to the D-Bus reference implementation. It is exclusively written for Linux systems, and makes use of many modern features provided by recent Linux kernel releases.
Security Fix(es):
* dbus-broker: a stack buffer over-read if a malicious Exec line is supplied (CVE-2022-31212)
* dbus-broker: null pointer reference when supplying a malformed XML config file (CVE-2022-31213)
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.

Vulnerability from csaf_redhat - Published: 2022-09-20 13:41 - Updated: 2025-11-21 18:33Summary
Red Hat Security Advisory: dbus-broker security update
Notes
Topic
An update for dbus-broker is now available for Red Hat Enterprise Linux 9.
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.
Details
dbus-broker is an implementation of a message bus as defined by the D-Bus specification. Its aim is to provide high performance and reliability, while keeping compatibility to the D-Bus reference implementation. It is exclusively written for Linux systems, and makes use of many modern features provided by recent Linux kernel releases.
Security Fix(es):
* dbus-broker: a stack buffer over-read if a malicious Exec line is supplied (CVE-2022-31212)
* dbus-broker: null pointer reference when supplying a malformed XML config file (CVE-2022-31213)
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.

Its aim is to provide high performance and reliability, while keeping compatibility to the D-Bus reference implementation. It is exclusively written for Linux systems, and makes use of many modern features provided by recent Linux kernel releases.\n\nSecurity Fix(es):\n\n* dbus-broker: a stack buffer over-read if a malicious Exec line is supplied (CVE-2022-31212)\n\n* dbus-broker: null pointer reference when supplying a malformed XML config file (CVE-2022-31213)\n\nFor 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.",
