  - An error in the Windows Data Sharing Service which improperly handles file operations.

    system using RDP and sends specially crafted requests.

  - An error in the way that Windows handles objects in memory.

  - An error in Active Directory Forest trusts due to a default setting that lets an
    attacker in the trusting forest request delegation of a TGT for an identity from
    the trusted forest.

  - An error in the way that the Windows Search Indexer handles objects in memory.
