    Layout Randomization (KASLR) bypass.

  - The Adobe Type Manager Library in Windows improperly handles specially
    crafted embedded fonts.

  - The Windows kernel fails to properly validate permissions, allowing an
    attacker to inappropriately interact with the filesystem from low
    integrity level user-mode applications.");
