    It was discovered that the ContainerNode::parserRemoveChild function in Blink mishandled widget updates 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-2016-1630)

    It was discovered that the PPB_Flash_MessageLoop_Impl::InternalRun

    function in Chromium mishandled nested message loops. If a user were tricked in to opening a specially
    crafted website, an attacker could potentially exploit this to bypass same-origin restrictions.
    (CVE-2016-1631)

    Multiple use-after-frees were discovered in Blink. If a user were tricked in to opening a specially
    crafted website, an attacker could potentially exploit these to cause a denial of service via renderer
    crash or execute arbitrary code with the privileges of the sandboxed render process. (CVE-2016-1633,
    CVE-2016-1634, CVE-2016-1644)

    It was discovered that the PendingScript::notifyFinished function in Blink relied on memory-cache
    information about integrity-check occurrences instead of integrity-check successes. If a user were tricked
    in to opening a specially crafted website, an attacker could potentially exploit this to bypass
    Subresource Integrity (SRI) protections. (CVE-2016-1636)

    It was discovered that the SkATan2_255 function in Skia mishandled arctangent calculations. If a user were
    tricked in to opening a specially crafted website, an attacker could potentially exploit this to obtain
    sensitive information. (CVE-2016-1637)

    A use-after-free 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 via application crash, or
    execute arbitrary code with the privileges of the user invoking the program. (CVE-2016-1641)

    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 via application crash or execute arbitrary code with the privileges of the user invoking the
    program. (CVE-2016-1642)

    A type-confusion bug was discovered in Blink. If a user were tricked in to opening a specially crafted
    website, an attacker could potentially exploit this to cause a denial of service via renderer crash or
    execute arbitrary code with the privileges of the sandboxed render process. (CVE-2016-1643)

    Multiple security issues were discovered in V8. 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 via renderer crash or execute arbitrary code with the privileges of the sandboxed render process.
    (CVE-2016-2843)

    An invalid cast was discovered in Blink. If a user were tricked in to opening a specially crafted website,
    an attacker could potentially exploit this to cause a denial of service via renderer crash or execute
    arbitrary code with the privileges of the sandboxed render process. (CVE-2016-2844)

    It was discovered that the Content Security Policy (CSP) implementation in Blink did not ignore a URL's
    path component in the case of a ServiceWorker fetch. If a user were tricked in to opening a specially
    crafted website, an attacker could potentially exploit this to obtain sensitive information.
    (CVE-2016-2845)
