A vulnerability was found in fso-gsm, fso-frameworkd and fso-usaged on Debian (unknown version). It has been rated as problematic. Affected by this issue is an unknown code block of the file /etc/dbus-1/system.d/*.conf of the component D-Bus Security Policy. The manipulation as part of a Message leads to a access control vulnerability. Using CWE to declare the problem leads to CWE-264. Impacted is confidentiality, integrity, and availability. CVE summarizes:

The D-Bus security policy files in /etc/dbus-1/system.d/*.conf in fso-gsmd 0.12.0-3, fso-frameworkd 0.9.5.9+git20110512-4, and fso-usaged 0.12.0-2 as packaged in Debian, the upstream cornucopia.git (fsoaudiod, fsodatad, fsodeviced, fsogsmd, fsonetworkd, fsotdld, fsousaged) git master on 2015-01-19, the upstream framework.git 0.10.1 and git master on 2015-01-19, phonefsod 0.1+git20121018-1 as packaged in Debian, Ubuntu and potentially other packages, and potentially other fso modules do not properly filter D-Bus message paths, which might allow local users to cause a denial of service (dbus-daemon memory consumption), or execute arbitrary code as root by sending a crafted D-Bus message to any D-Bus system service.

The bug was discovered 01/27/2015. The weakness was released 09/26/2017 by Simon McVittie (oss-sec). The advisory is available at openwall.com.
