Privilege Escalation via DBUS_SYSTEM_BUS_ADDRESS Environment Variable in libgio

CVE-2012-4425 · MEDIUM Severity

AV:L/AC:M/AU:N/C:C/I:C/A:C

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.
