  - A vulnerability exists, known as SWEET32, in the 3DES
    and Blowfish algorithms due to the use of weak 64-bit
    block ciphers by default. A man-in-the-middle attacker
    who has sufficient resources can exploit this
    vulnerability, via a 'birthday' attack, to detect a
    collision that leaks the XOR between the fixed secret
    and a known plaintext, allowing the disclosure of the
    secret text, such as secure HTTPS cookies, and possibly
    resulting in the hijacking of an authenticated session.
    (CVE-2016-2183)

  - A flaw exists in the Core subcomponent, specifically in
    the libcurl library, due to improper validation of TLS
    certificates. An authenticated, remote attacker with the
    ability to intercept network traffic can exploit this
    issue to disclose or manipulate transmitted data by
    spoofing the TLS/SSL server using a certificate that
    appears valid. Note that this issue only affects
    versions 5.2 and 5.3. (CVE-2016-3739)

  - A flaw exists in cURL and libcurl when loading dynamic
    link library (DLL) files security.dll, secur32.dll, or

    2003 standard instead of the IDNA 2008 standard, which
    can result in incorrect translation of a domain name.
    An unauthenticated, remote attacker can exploit this to
    cause network traffic to be redirected to a different
    host than intended. (CVE-2016-8625)

  - A flaw exists in Apache Tomcat within the
    catalina/mbeans/JmxRemoteLifecycleListener.java class
    that is triggered during the deserialization of Java
    objects. An unauthenticated, remote attacker can exploit
    this to execute arbitrary code. (CVE-2016-8735)

  - A flaw exists in the Web Server component (Apache HTTP
    Server) when handling whitespace patterns in User-Agent
    headers. An authenticated, remote attacker can exploit
    this, via a specially crafted User-Agent header, to
    cause incorrect processing of sequences of requests,
    resulting in incorrectly interpreting responses,
    polluting the cache, or disclosing content from one
    request to a second downstream user-agent.
    (CVE-2016-8743)

  - A NULL pointer dereference flaw exists within file
    ssl/statem/statem_clnt.c when handling parameters for
    the DHE or ECDHE key exchanges. An unauthenticated,

    parameters, to cause a denial of service condition.
    (CVE-2017-3730)

  - A out-of-bounds read error exists exists in the Core
    subcomponent, specifically in OpenSSL, when handling
    packets using the CHACHA20/POLY1305 or RC4-MD5 ciphers.
    An unauthenticated, remote attacker can exploit this,
    via specially crafted truncated packets, to cause a
    denial of service condition. (CVE-2017-3731)

  - A carry propagating error exists in the x86_64
    Montgomery squaring implementation that may cause the
    BN_mod_exp() function to produce incorrect results. An
    unauthenticated, remote attacker with sufficient
    resources can exploit this to obtain sensitive
    information regarding private keys. Note that this issue
    is very similar to CVE-2015-3193. Moreover, the attacker
    would additionally need online access to an unpatched
    system using the target private key in a scenario with
    persistent DH parameters and a private key that is
    shared between multiple clients. For example, this can
    occur by default in OpenSSL DHE based SSL/TLS cipher
    suites. (CVE-2017-3732)
