Ispravljena je ranjivost programskog alata GDM (eng. GNOME Display Manager). Radi se o alatu koji se koristi u distribucijama operacijskih sustava Unix i Linux za prijavu korisnika te za pokretanje grafičkog korisničkog sučelja. Propust se odnosi na činjenicu da je GDM dopuštao lokalnim korisnicima promjenu vlasništva nad proizvoljnim datotekama. Navedeni postupak bio je izvediv napadom, pomoću simboličke poveznice, na dmrc ili na datoteku sa slikom korisnika koja se nalazi u direktoriju /var/cache/gdm/. Kako bi korisnici izbjegli uočeni problem trebaju obaviti nadogradnju.
