Descriptions

spice-gtk 0.14, and possibly other versions, invokes the polkit authority using the insecure polkit_unix_process_new API function, which allows local users to bypass intended access restrictions by leveraging a PolkitUnixProcess PolkitSubject race condition via a (1) setuid process or (2) pkexec process, a related issue to CVE-2013-4288.

spice-gtk 0.14, y posiblemente otras versiones, invoca la autoridad polkit utilizando la función insegura polkit_unix_process_new API, que permite a usuarios locales eludir las restricciones de acceso destinadas para aprovechar un condición de carrera en PolkitSubject PolkitUnixProcess a través de un (1) proceso setuid o (2) el proceso pkexec , un tema relacionado con CVE-2013-4288.

The spice-gtk packages provide a GIMP Toolkit widget for SPICE clients. Both Virtual Machine Manager and Virtual Machine Viewer can make use of this widget to access virtual machines using the SPICE protocol. spice-gtk communicated with PolicyKit for authorization via an API that is vulnerable to a race condition. This could lead to intended PolicyKit authorizations being bypassed. This update modifies spice-gtk to communicate with PolicyKit via a different API that is not vulnerable to the race condition.
