Description Huzaifa S. Sidhpurwala 2012-09-14 02:44:06 UTC 
It was discovered that the spice-gtk setuid helper application, spice-client-glib-usb-acl-helper, did not clear the environment variables read by the libraries it uses. A local attacker could possibly use this flaw to escalate their privileges by setting specific environment variables before running the helper application. 

This flaw is similar to  CVE-2012-3524
