Impact: Moderate
Public: 2012-09-12
Bugzilla: 857283: CVE-2012-4425 spice-gtk/glib: Possible privilege escalation via un-sanitized environment variable

Details

The MITRE CVE dictionary describes this issue as:

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.
