The _dbus_validate_signature_with_reason function (dbus-marshal-validate.c) in D-Bus (aka DBus) before 1.2.14 uses incorrect logic to validate a basic type, which allows remote attackers to spoof a signature via a crafted key. NOTE: this is due to an incorrect fix for CVE-2008-3834.

Security readout for executives and security teams

CVE-2009-1189 is an old D-Bus flaw where signature validation logic could be bypassed with crafted input. D-Bus is common on Linux and Unix-like systems, so exposure depends on whether legacy systems still run versions before 1.2.14 or vendor packages that carried the faulty fix. Most modern environments are likely patched. Risk remains for legacy Linux, Unix-like, appliance, or virtualization management systems using old D-Bus packages, including systems covered by historical Ubuntu, Red Hat, VMware, Juniper, or OVAL references. Treat this as legacy hygiene with targeted urgency. It is not KEV-listed in the provided data, but D-Bus is foundational software, and old unpatched systems can create hidden trust-boundary risk. Mitigation focus: Upgrade D-Bus to 1.2.14 or a vendor-fixed package.; Check vendor advisories for distribution-specific package names and backports.; Prioritize unsupported legacy systems and embedded appliances for review..
