    An unspecified security issue was discovered in Blink. If a user were tricked in to opening a specially
    crafted website, an attacker could potentially exploit this to bypass same-origin restrictions.
    (CVE-2016-1673)

    An issue was discovered with Document reattachment in Blink in some circumstances. If a user were tricked
    in to opening a specially crafted website, an attacker could potentially exploit this to bypass same-
    origin restrictions. (CVE-2016-1675)

    A type confusion bug was discovered in V8. If a user were tricked in to opening a specially crafted
    website, an attacker could potentially exploit this to obtain sensitive information. (CVE-2016-1677)

    A heap overflow was discovered in V8. If a user were tricked in to opening a specially crafted website, an
    attacker could potentially exploit this to cause a denial of service (application crash) or execute
    arbitrary code. (CVE-2016-1678)

    A use-after-free was discovered in the V8ValueConverter implementation in Chromium in some circumstances.
    If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit
    this to cause a denial of service (application crash) or execute arbitrary code. (CVE-2016-1679)

    A use-after-free was discovered in Skia. If a user were tricked in to opening a specially crafted website,
    an attacker could potentially exploit this to cause a denial of service (application crash) or execute
    arbitrary code. (CVE-2016-1680)

    A security issue was discovered in ServiceWorker registration in Blink in some circumstances. If a user
    were tricked in to opening a specially crafted website, an attacker could potentially exploit this to
    bypass Content Security Policy (CSP) protections. (CVE-2016-1682)

    An out-of-bounds memory access was discovered in libxslt. If a user were tricked in to opening a specially
    crafted website, an attacker could potentially exploit this to cause a denial of service (application
    crash) or execute arbitrary code. (CVE-2016-1683)

    An integer overflow was discovered in libxslt. If a user were tricked in to opening a specially crafted
    website, an attacker could potentially exploit this to cause a denial of service (application crash or
    resource consumption). (CVE-2016-1684)

    An out-of-bounds read was discovered in the regular expression implementation in V8. If a user were
    tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a
    denial of service (application crash). (CVE-2016-1688)

    A heap overflow was discovered in Chromium. If a user were tricked in to opening a specially crafted
    website, an attacker could potentially exploit this to cause a denial of service (application crash) or
    execute arbitrary code. (CVE-2016-1689)

    A heap overflow was discovered in Skia. If a user were tricked in to opening a specially crafted website,
    an attacker could potentially exploit this to cause a denial of service (application crash) or execute
    arbitrary code. (CVE-2016-1691)

    It was discovered that Blink permits cross-origin loading of stylesheets by a service worker even when the
    stylesheet download has an incorrect MIME type. If a user were tricked in to opening a specially crafted
    website, an attacker could potentially exploit this to bypass same-origin restrictions. (CVE-2016-1692)

    Multiple security issues were discovered in Chromium. If a user were tricked in to opening a specially
    crafted website, an attacker could potentially exploit these to read uninitialized memory, cause a denial
    of service (application crash) or execute arbitrary code. (CVE-2016-1695, CVE-2016-1703)

    It was discovered that Blink does not prevent frame navigation during DocumentLoader detach operations. If
    a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this
    to bypass same-origin restrictions. (CVE-2016-1697)

    A parameter sanitization bug was discovered in the devtools subsystem in Blink. An attacker could
    potentially exploit this to bypass intended access restrictions. (CVE-2016-1699)

    An out-of-bounds read was discovered in Skia. If a user were tricked in to opening a specially crafted
    website, an attacker could potentially exploit this to cause a denial of service (application crash).
