"According to its banner, the remote Apple TV device is a version prior

  - Multiple memory corruption vulnerabilities exist in
    WebKit due to improperly validated user-supplied input.
    A remote attacker, using a specially crafted website,
    can exploit these to execute arbitrary code.

    CVE-2015-1122, CVE-2015-1123, CVE-2015-1124)

  - An error exists in the IOKit objects due to improper
    validation of metadata used by an audio driver, which
    allows arbitrary code execution. (CVE-2015-1086)

  - An XML External Entity (XXE) injection vulnerability
    exists in the NSXMLParser due to improper handling of
    XML files, which allows information disclosure.
    (CVE-2015-1092)

  - An error exists in the IOAcceleratorFamily that allows
    the kernel memory layout to be disclosed.
    (CVE-2015-1094)

  - A memory corruption vulnerability exists in the
    IOHIDFamily API that allows arbitrary code execution.
    (CVE-2015-1095)

  - An error exists in the IOHIDFamily due to improper
    bounds checking, which allows the kernel memory layout
    to be disclosed. (CVE-2015-1096)

  - An error exists in the MobileFrameBuffer due to improper
    bounds checking, which allows the kernel memory layout
    to be disclosed. (CVE-2015-1097)

  - A denial of service vulnerability exists in the
    setreuid() system call due to a race condition.
    (CVE-2015-1099)

  - An out-of-bounds memory error exists in the kernel that
    allows a denial of service attack or information
    disclosure. (CVE-2015-1100)

  - A memory corruption vulnerability exists in the kernel
    that allows arbitrary code execution. (CVE-2015-1101)

  - A denial of service vulnerability exists due to a state
    inconsistency in the processing of TCP headers, which
    can only be exploited from an adjacent network.
    (CVE-2015-1102)

  - A vulnerability exists that allows a man-in-the-middle
    attacker to redirect traffic via ICMP redirects.
    (CVE-2015-1103)

  - A security bypass vulnerability exists due to the
    system treating remote IPv6 packets as local packets,
    which allows an attacker to bypass network filters.
    (CVE-2015-1104)

  - A denial of service vulnerability exists due to improper
    processing of TCP out-of-band data, which allows a
    denial of service by a remote attacker. (CVE-2015-1105)

  - An information disclosure vulnerability exists due to
    unique identifiers being sent to remote servers when
    downloading assets for a podcast. (CVE-2015-1110)

  - An information disclosure vulnerability exists in the
    third-party application sandbox that allows hardware
    identifiers to be accessible by other applications.
    (CVE-2015-1114)

  - A privilege escalation vulnerability exists in the
    setreuid() and setregid() system calls due to a failure
    to drop privileges permanently. (CVE-2015-1117)

  - A memory corruption vulnerability exists due to improper
    bounds checking when processing configuration profiles,
    which allows a denial of service attack. (CVE-2015-1118)");
