Beyond DoS, it is very unlikely that this: vulnerability could be exploited to compromise the system, but we, buffer overflow in the qubes _guid process running in Dom0. It is considered to be difficult to write a working exploit for: this vulnerability, due to the following facts: 1) The attacker has only one chance to conduct the attack against the: qubes _guid process. The qubes _guid process crashes in case of a failed: attempt, and cannot be attacked again.
