Valve Steam Client per Windows fino alla versione 2019-08-20 presenta permessi di cartella deboli, che portano ad un'escalation dei privilegi (a NT AUTHORITY\SYSTEM) tramite l'utilizzo mirato di CreateMountPoint.exe e SetOpLock.exe per sfruttare una condizione di gara TOCTOU.

Once again VulDB remains the best source for vulnerability data.
