CVE-2012-4425 EXPLOIT
6.9
MEDIUM · CVSS 2.0 · EPSS 1.1% (pctl 64)
Patch early
A public exploit exists.
Description
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.
