Otkrivena je ranjivost biblioteke libvirt koja omogućuje izvođenje različitih virtualnih rješenja, kao što su KVM (eng. Kernel-based Virtual Machine) i Xen, putem uobičajenih sučelja. Radi se o inačici namijenjenoj operacijskom sustavu Fedora 15. Sigurnosni propust vezan je uz rad dretvi spomenute biblioteke. Naime, problem nastaje kada više dretvi istovremeno izvještava o pogreškama. Takve pogreške mogu se pomiješati ili izmijeniti, a to može rezultirati prekidom rada biblioteke odnosno uskraćivanjem njene usluge. Svim korisnicima, kao rješenje opisanog problema, savjetuje se standardna nadogradnja.
