Format Driver that is affected by two vulnerabilities :

  - The driver does not properly index an array when
    parsing OpenType fonts, which could allow a remote
    attacker to run arbitrary code in kernel mode.
    (CVE-2010-3956)

  - The driver does not properly reset a pointer when
    freeing memory, resulting in a 'double free' condition,
    which could allow a remote attacker to run arbitrary
    code in kernel mode. (CVE-2010-3957)

  - The driver does not properly parse the CMAP table when
    rendering a specially crafted OpenType font, which
    could allow a local attacker to run arbitrary code in
    kernel mode. (CVE-2010-3959)"
