  - An overflow condition exists in the BN_bn2dec() function     in bn_print.c due to improper validation of     user-supplied input when handling BIGNUM values. An     unauthenticated, remote attacker can exploit this to     crash the process. (CVE-2016-2182)

  - 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 tls_decrypt_ticket() function in     t1_lib.c due to improper handling of ticket HMAC     digests. An unauthenticated, remote attacker can exploit     this, via a ticket that is too short, to crash the     process, resulting in a denial of service.
    (CVE-2016-6302)

  - An integer overflow condition exists in the     MDC2_Update() function in mdc2dgst.c due to improper     validation of user-supplied input. An unauthenticated,     remote attacker can exploit this to cause a heap-based     buffer overflow, resulting in a denial of service     condition or possibly the execution of arbitrary code.
    (CVE-2016-6303)

  - A flaw exists in the ssl_parse_clienthello_tlsext()     function in t1_lib.c due to improper handling of overly     large OCSP Status Request extensions from clients. An     unauthenticated, remote attacker can exploit this, via     large OCSP Status Request extensions, to exhaust memory     resources, resulting in a denial of service condition.
    (CVE-2016-6304)

  - A flaw exists in the SSL_peek() function in     rec_layer_s3.c due to improper handling of empty     records. An unauthenticated, remote attacker can exploit     this, by triggering a zero-length record in an SSL_peek     call, to cause an infinite loop, resulting in a denial     of service condition. (CVE-2016-6305)

  - An out-of-bounds read error exists in the certificate     parser that allows an unauthenticated, remote attacker     to cause a denial of service via crafted certificate     operations. (CVE-2016-6306)

  - A denial of service vulnerability exists in the     state-machine implementation due to a failure to check     for an excessive length before allocating memory. An     unauthenticated, remote attacker can exploit this, via a     crafted TLS message, to exhaust memory resources.
    (CVE-2016-6307)

Note that these issues only affects devices with J-Web or the SSL service for JUNOScript enabled.

According to its banner, the version of OpenSSL on the remote host is 1.0.1 prior to 1.0.1u, or 1.0.2 prior to 1.0.2i.  It is therefore affected by the following vulnerabilities :

 - A flaw exists in 'ssl/s3_srvr.c', 'ssl/ssl_sess.c', and 'ssl/t1_lib.c' that may under certain circumstances lead to integer overflows and allow an attacker to have an unspecified impact. (CVE-2016-2177)
 - A flaw exists in 'crypto/dsa/dsa_ossl.c' that is triggered as the DSA signing algorithm does not properly run in constant time.  This may potentially allow a context-dependent attacker to conduct e.g. a side channel attack and gain unauthorized access to DSA key information. (CVE-2016-2178)
 - A flaw exists that is due to the system not handling fragmented DTLS buffered messages correctly.  There are two scenarios where messages could result in the queue not being cleared and memory not being freed.  The first occurs when a full message is received after a fragment of the same message, and the system uses the full message while ignoring the fragmented message without removing it from queue.  The second occurs when a peer sends a 'future' message with extraneous packets containing a sequence number higher than the Finished message, resulting in the packets not being removed from queue.  With a saturation of either type of message, a remote attacker can exhaust up to 1500k of memory per connection, exhausting memory leading to a remote denial of service. (CVE-2016-2179)
 - An out-of-bounds read flaw exists in the 'TS_OBJ_print_bio()' function in 'crypto/ts/ts_lib.c'.  This may allow a context-dependent attacker to have an unspecified impact that may potentially include crashing a process linked against the library or disclosing memory contents. (CVE-2016-2180)
 - A flaw exists in the DTLS implementation that is triggered when handling epoch sequence numbers in records.  This may allow a remote attacker to cause legitimate packets to be dropped. (CVE-2016-2181)
 - An overflow condition exists in the 'BN_bn2dec()' function in 'crypto/bn/bn_print.c'.  The issue is triggered as certain input is not properly validated when handling BIGNUM values. This may allow a context-dependent attacker to cause a buffer overflow, resulting in a denial of service in a process linked against the library. (CVE-2016-2182)
 - A flaw exists in the 'tls_decrypt_ticket()' function in 'ssl/t1_lib.c' that is triggered during the handling of ticket HMAC digest.  This may allow a remote attacker to crash the service. (CVE-2016-6302)
 - An overflow condition exists in the 'MDC2_Update()' function in 'crypto/mdc2/mdc2dgst.c' that is triggered as certain input is not properly validated.  This may allow a context-dependent attacker to cause a heap-based buffer overflow, crashing a process linked against the library or potentially allowing the execution of arbitrary code. (CVE-2016-6303)
 - A flaw exists in the 'ssl_parse_clienthello_tlsext()' function in 'ssl/t1_lib.c' that is triggered when handling overly large OCSP Status Request extensions from clients.  This may allow a remote attacker to exhaust available memory in a process linked against the library. (CVE-2016-6304)
 - An out-of-bounds read flaw exists that is triggered when handling client certificate, client certificate request, and server certificate messages.  This may allow a remote attacker to potentially crash a process linked against the library. (CVE-2016-6306)
