  - A heap buffer overflow condition exists in the     EVP_EncryptUpdate() function within file     crypto/evp/evp_enc.c that is triggered when handling a     large amount of input data after a previous call occurs     to the same function with a partial block. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition. (CVE-2016-2106)

  - A remote code execution vulnerability exists in the     ASN.1 encoder due to an underflow condition that occurs     when attempting to encode the value zero represented as     a negative integer. An unauthenticated, remote attacker     can exploit this to corrupt memory, resulting in the     execution of arbitrary code. (CVE-2016-2108)

  - Multiple unspecified flaws exist in the d2i BIO     functions when reading ASN.1 data from a BIO due to     invalid encoding causing a large allocation of memory.
    An unauthenticated, remote attacker can exploit these to     cause a denial of service condition through resource     exhaustion. (CVE-2016-2109)

  - Multiple integer overflow conditions exist in s3_srvr.c,     ssl_sess.c, and t1_lib.c due to improper use of pointer     arithmetic for heap-buffer boundary checks. An     unauthenticated, remote attacker can exploit this to     cause a denial of service. (CVE-2016-2177)

  - An information disclosure vulnerability exists in the     dsa_sign_setup() function in dsa_ossl.c due to a failure     to properly ensure the use of constant-time operations.
    An unauthenticated, remote attacker can exploit this,     via a timing side-channel attack, to disclose DSA key     information. (CVE-2016-2178)

  - An out-of-bounds read error exists in the X.509 Public     Key Infrastructure Time-Stamp Protocol (TSP)     implementation. An unauthenticated, remote attacker can     exploit this, via a crafted time-stamp file that is     mishandled by the 'openssl ts' command, to cause     denial of service or to disclose sensitive information.
    (CVE-2016-2180)

  - 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.

The remote host is affected by the vulnerability described in GLSA-201612-16 (OpenSSL: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in OpenSSL. Please review       the CVE identifiers and the International Association for Cryptologic       Research&rsquo;s (IACR) paper, &ldquo;Make Sure DSA Signing Exponentiations       Really are Constant-Time&rdquo; for further details.
  Impact :

    Remote attackers could cause a Denial of Service condition or have other       unspecified impacts. Additionally, a time based side-channel attack may       allow a local attacker to recover a private DSA key.
  Workaround :

    There is no known workaround at this time.

According to its banner, the version of OpenSSL on the remote host is prior to 1.1.0a and is affected by the following vulnerabilities :

 - 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)
 - A flaw exists in the 'SSL_peek()' function in 'ssl/record/rec_layer_s3.c' that is triggered during the handling of an empty record.  This may allow a remote attacker to cause SSL or TLS to hang in a process linked against the library. (CVE-2016-6305)
 - A flaw exists in the 'tls_get_message_header()' function in 'ssl/statem/statem_lib.c' that is triggered when handling TLS messages.  With a specially crafted request, a remote attacker can cause a process linked against the library to exhaust available memory. (CVE-2016-6307)
According to the vendor, this issue will only have a security impact if one of the following conditions are met :
 1) The application does not call 'SSL_free()' in a timely manner in the event that the connection fails,
 2) The application is working in a constrained environment where there is very little free memory, or
 3) The attacker initiates multiple connection attempts such that there are multiple connections in a state where memory has been allocated for the connection,  'SSL_free()' has not yet been called, and there is insufficient memory to service the multiple requests.
 - A flaw exists in the 'dtls1_preprocess_fragment()' function in 'ssl/statem/statem_dtls.c' that is triggered during the handling of excessively long DTLS messages.  This may allow a remote attacker to exhaust memory resources in a process linked against the library.  (CVE-2016-6308)

The version of OpenSSL installed on the remote host is prior to 1.1.0a. It is, therefore, affected by multiple vulnerabilities as referenced in the 1.1.0a advisory.

  - The ssl3_read_bytes function in record/rec_layer_s3.c in OpenSSL 1.1.0 before 1.1.0a allows remote     attackers to cause a denial of service (infinite loop) by triggering a zero-length record in an SSL_peek     call. (CVE-2016-6305)

  - Multiple memory leaks in t1_lib.c in OpenSSL before 1.0.1u, 1.0.2 before 1.0.2i, and 1.1.0 before 1.1.0a     allow remote attackers to cause a denial of service (memory consumption) via large OCSP Status Request     extensions. (CVE-2016-6304)

  - statem/statem_dtls.c in the DTLS implementation in OpenSSL 1.1.0 before 1.1.0a allocates memory before     checking for an excessive length, which might allow remote attackers to cause a denial of service (memory     consumption) via crafted DTLS messages. (CVE-2016-6308)

  - The state-machine implementation in OpenSSL 1.1.0 before 1.1.0a allocates memory before checking for an     excessive length, which might allow remote attackers to cause a denial of service (memory consumption) via     crafted TLS messages, related to statem/statem.c and statem/statem_lib.c. (CVE-2016-6307)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
