FKIE_CVE-2012-4425

Vulnerability from fkie_nvd - Published: 2012-09-18 17:55 - Updated: 2026-06-16 23:44
Severity
Summary
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.
