"The remote Windows host is affected by the following vulnerabilities :

  - Multiple elevation of privilege vulnerabilities exist
    that are related to the handling of objects in memory.
    A local attacker can exploit these, via a crafted
    application, to run arbitrary code in kernel mode.
    (CVE-2015-6100, CVE-2015-6101)

  - Multiple information disclosure vulnerabilities exist
    due to a failure to properly initialize memory
    addresses. A local attacker can exploit these, via a
    specially crafted application, to bypass the Kernel
    Address Space Layout Randomization (KASLR) and retrieve
    the base address of the Kernel driver from a compromised
    process. (CVE-2015-6102, CVE-2015-6109)

  - Multiple remote code execution vulnerabilities exist
    in the Adobe Type Manager Library due to improper
    handling of specially crafted fonts. An unauthenticated,
    remote attacker can exploit these, via a crafted
    document or web page, to execute arbitrary code.
    (CVE-2015-6103, CVE-2015-6104)

  - A security feature bypass vulnerability exists due to
    improper validation of permissions. A local attacker can
    exploit this to interact with the file system in an
    inappropriate manner to modify files, by using a
    crafted, low-integrity-level, user-mode application.
    (CVE-2015-6113)");
