CVE-2011-2200: n/a vulnerability

CVE-2011-2200: The _dbus_header_byteswap function in dbus-marshal-header.c in D-Bus (aka DBus) 1.2.x before 1.2.28, 1.4.x...

The _dbus_header_byteswap function in dbus-marshal-header.c in D-Bus (aka DBus) 1.2.x before 1.2.28, 1.4.x before 1.4.12, and 1.5.x before 1.5.4 does not properly handle a non-native byte order, which allows local users to cause a denial of service (connection loss), obtain potentially sensitive information, or conduct unspecified state-modification attacks via crafted messages.

Security readout for executives and security teams

D-Bus versions from 2011 mishandled messages using a byte order different from the host system. A local user or process could disrupt D-Bus connections, and the CVE also notes possible sensitive information exposure or unspecified state changes. The source bundle does not show remote exploitation or KEV listing. Likely exposure is legacy Linux, Unix, embedded, or appliance environments still running affected D-Bus versions. The provided evidence indicates local-user exposure, not internet-facing reachability. Modern supported distributions are likely patched, but inherited appliances and frozen images should be checked. Treat as a legacy hygiene issue with moderate business urgency. It is local-only in the provided evidence and not KEV-listed, but D-Bus is a core system component, so unpatched legacy endpoints or appliances can still create operational risk. Mitigation focus: Upgrade D-Bus to 1.2.28, 1.4.12, 1.5.4, or later supported vendor packages.; Apply relevant OS vendor advisories, including Red Hat guidance where applicable.; Prioritize unsupported systems, appliances, and embedded images that bundle old D-Bus releases..
