CVE-2014-8148
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe default D-Bus access control rule in Midgard2 10.05.7.1 allows local users to send arbitrary method calls or signals to any process on the system bus and possibly execute arbitrary code with root privileges.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceMidgard2 10.05.7.1 ships with an overly permissive default D-Bus access control rule that allows any local user to send arbitrary method calls or signals to any process on the system bus, potentially enabling root privilege escalation.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify if Midgard2 is installedOn openSUSE, run: rpm -qa | grep -i midgard2Affected if No Midgard2 package is found, then this CVE does not apply
-
Check the installed Midgard2 versionRun: rpm -q midgard2 or rpm -qi midgard2 to retrieve the version numberAffected if The installed version is 10.05.7.1 (exact match to the affected version)
-
Locate the Midgard2 D-Bus configuration fileLook for D-Bus policy files in /etc/dbus-1/system.d/ directory, typically named midgard2.conf or similar. Run: ls -la /etc/dbus-1/system.d/ | grep -i midgardAffected if No Midgard2-specific D-Bus configuration file exists in the system.d directory, the default permissive rule may not be present
-
Examine the D-Bus access control policyRead the Midgard2 D-Bus configuration file with: cat /etc/dbus-1/system.d/midgard2.conf (or the actual filename found). Look for <policy> sections with user="anyone" or a wildcard that allows any local userAffected if The configuration contains a policy with user="anyone" or similar permissive setting that grants all local users the ability to send method calls or signals without restriction
A system is affected if Midgard2 version 10.05.7.1 is installed AND the D-Bus configuration file contains an overly permissive policy allowing any local user to send arbitrary method calls or signals on the system bus.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataRestrict the D-Bus access control configuration to limit which users and processes can send method calls or signals, following the principle of least privilege for D-Bus policy rules.
