CVE-2012-4425 – libdbus - 'DBUS_SYSTEM_BUS_ADDRESS' Local Privilege Escalation

https://notcve.org/view.php?id=CVE-2012-4425

libgio, when used in setuid or other privileged programs in spice-gtk and possibly other products, allows local users to gain privileges and execute arbitrary code via the DBUS_SYSTEM_BUS_ADDRESS environment variable. NOTE: it could be argued that this is a vulnerability in the applications that do not cleanse environment variables, not in libgio itself. libgio, cuando se utiliza setuid u otros programas con privilegios en spice-gtk y posiblemente otros productos, permite a usuarios locales obtener privilegios y ejecutar código de su elección a través de la variable de entorno DBUS_SYSTEM_BUS_ADDRESS. NOTA: Se podría argumentar que se trata de una vulnerabilidad en las aplicaciones que limpian las variables de entorno, no solo en libgio en sí. • https://www.exploit-db.com/exploits/21323 http://permalink.gmane.org/gmane.linux.redhat.fedora.extras.cvs/853051 http://rhn.redhat.com/errata/RHSA-2012-1284.html http://www.exploit-db.com/exploits/21323 http://www.openwall.com/lists/oss-security/2012/09/12/6 http://www.openwall.com/lists/oss-security/2012/09/14/2 http://www.openwall.com/lists/oss-security/2012/09/17/2 http://www.securityfocus.com/bid/55555 http://www.spinics.net/lists/spice-devel/msg01940 • CWE-264: Permissions, Privileges, and Access Controls •
