The version of OpenSSL installed on the remote host is prior to 1.0.0r. It is, therefore, affected by multiple vulnerabilities as referenced in the 1.0.0r advisory.

  - An oracle protection mechanism in the get_client_master_key function in s2_srvr.c in the SSLv2     implementation in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before     1.0.2a overwrites incorrect MASTER-KEY bytes during use of export cipher suites, which makes it easier for     remote attackers to decrypt TLS ciphertext data by leveraging a Bleichenbacher RSA padding oracle, a     related issue to CVE-2016-0800. (CVE-2016-0704)

  - The get_client_master_key function in s2_srvr.c in the SSLv2 implementation in OpenSSL before 0.9.8zf,     1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a accepts a nonzero CLIENT-MASTER-KEY     CLEAR-KEY-LENGTH value for an arbitrary cipher, which allows man-in-the-middle attackers to determine the     MASTER-KEY value and decrypt TLS ciphertext data by leveraging a Bleichenbacher RSA padding oracle, a     related issue to CVE-2016-0800. (CVE-2016-0703)

  - The SSLv2 implementation in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2     before 1.0.2a allows remote attackers to cause a denial of service (s2_lib.c assertion failure and daemon     exit) via a crafted CLIENT-MASTER-KEY message. (CVE-2015-0293)

  - The PKCS#7 implementation in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2     before 1.0.2a does not properly handle a lack of outer ContentInfo, which allows attackers to cause a     denial of service (NULL pointer dereference and application crash) by leveraging an application that     processes arbitrary PKCS#7 data and providing malformed data with ASN.1 encoding, related to     crypto/pkcs7/pk7_doit.c and crypto/pkcs7/pk7_lib.c. (CVE-2015-0289)

  - The ASN1_item_ex_d2i function in crypto/asn1/tasn_dec.c in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r,     1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a does not reinitialize CHOICE and ADB data structures, which     might allow attackers to cause a denial of service (invalid write operation and memory corruption) by     leveraging an application that relies on ASN.1 structure reuse. (CVE-2015-0287)

  - The ASN1_TYPE_cmp function in crypto/asn1/a_type.c in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1     before 1.0.1m, and 1.0.2 before 1.0.2a does not properly perform boolean-type comparisons, which allows     remote attackers to cause a denial of service (invalid read operation and application crash) via a crafted     X.509 certificate to an endpoint that uses the certificate-verification feature. (CVE-2015-0286)

  - Use-after-free vulnerability in the d2i_ECPrivateKey function in crypto/ec/ec_asn1.c in OpenSSL before     0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a might allow remote attackers to     cause a denial of service (memory corruption and application crash) or possibly have unspecified other     impact via a malformed Elliptic Curve (EC) private-key file that is improperly handled during import.
    (CVE-2015-0209)

  - The X509_to_X509_REQ function in crypto/x509/x509_req.c in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r,     1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a might allow attackers to cause a denial of service (NULL     pointer dereference and application crash) via an invalid certificate key. (CVE-2015-0288)

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2015:0715 advisory.

    OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3)     and Transport Layer Security (TLS v1) protocols, as well as a     full-strength, general purpose cryptography library.

    An invalid pointer use flaw was found in OpenSSL's ASN1_TYPE_cmp()     function. A remote attacker could crash a TLS/SSL client or server using     OpenSSL via a specially crafted X.509 certificate when the     attacker-supplied certificate was verified by the application.
    (CVE-2015-0286)

    An integer underflow flaw, leading to a buffer overflow, was found in the     way OpenSSL decoded malformed Base64-encoded inputs. An attacker able to     make an application using OpenSSL decode a specially crafted Base64-encoded     input (such as a PEM file) could use this flaw to cause the application to     crash. Note: this flaw is not exploitable via the TLS/SSL protocol because     the data being transferred is not Base64-encoded. (CVE-2015-0292)

    A denial of service flaw was found in the way OpenSSL handled SSLv2     handshake messages. A remote attacker could use this flaw to cause a     TLS/SSL server using OpenSSL to exit on a failed assertion if it had both     the SSLv2 protocol and EXPORT-grade cipher suites enabled. (CVE-2015-0293)

    A use-after-free flaw was found in the way OpenSSL imported malformed     Elliptic Curve private keys. A specially crafted key file could cause an     application using OpenSSL to crash when imported. (CVE-2015-0209)

    An out-of-bounds write flaw was found in the way OpenSSL reused certain     ASN.1 structures. A remote attacker could possibly use a specially crafted     ASN.1 structure that, when parsed by an application, would cause that     application to crash. (CVE-2015-0287)

    A NULL pointer dereference flaw was found in OpenSSL's X.509 certificate     handling implementation. A specially crafted X.509 certificate could cause     an application using OpenSSL to crash if the application attempted to     convert the certificate to a certificate request. (CVE-2015-0288)

    A NULL pointer dereference was found in the way OpenSSL handled certain     PKCS#7 inputs. An attacker able to make an application using OpenSSL     verify, decrypt, or parse a specially crafted PKCS#7 input could cause that     application to crash. TLS/SSL clients and servers using OpenSSL were not     affected by this flaw. (CVE-2015-0289)

According to its version number, the Splunk Enterprise hosted on the remote web server is 5.0.x prior to 5.0.13, 6.0.x prior to 6.0.9, or 6.1.x prior to 6.1.4. It is, therefore, affected by the following vulnerabilities related to the included OpenSSL library :

  - A security feature bypass vulnerability, known as FREAK     (Factoring attack on RSA-EXPORT Keys), exists due to the     support of weak EXPORT_RSA cipher suites with keys less     than or equal to 512 bits. A man-in-the-middle attacker     may be able to downgrade the SSL/TLS connection to use     EXPORT_RSA cipher suites which can be factored in a     short amount of time, allowing the attacker to intercept     and decrypt the traffic. (CVE-2015-0204)

  - A flaw exists in the DTLSv1_listen() function due to     state being preserved in the SSL object from one     invocation to the next. A remote attacker can exploit     this, via crafted DTLS traffic, to cause a segmentation     fault, resulting in a denial of service.
    (CVE-2015-0207)

  - A flaw exists in the rsa_item_verify() function due to     improper implementation of ASN.1 signature verification.
    A remote attacker can exploit this, via an ASN.1     signature using the RSA PSS algorithm and invalid     parameters, to cause a NULL pointer dereference,     resulting in a denial of service. (CVE-2015-0208)

  - A use-after-free condition exists in the     d2i_ECPrivateKey() function due to improper processing     of malformed EC private key files during import. A     remote attacker can exploit this to dereference or free     already freed memory, resulting in a denial of service     or other unspecified impact. (CVE-2015-0209)

  - A flaw exists in the ssl3_client_hello() function due to     improper validation of a PRNG seed before proceeding     with a handshake, resulting in insufficient entropy and     predictable output. This allows a man-in-the-middle     attacker to defeat cryptographic protection mechanisms     via a brute-force attack, resulting in the disclosure of     sensitive information. (CVE-2015-0285)

  - An invalid read flaw exists in the ASN1_TYPE_cmp()     function due to improperly performed boolean-type     comparisons. A remote attacker can exploit this, via a     crafted X.509 certificate to an endpoint that uses the     certificate-verification feature, to cause an invalid     read operation, resulting in a denial of service.
    (CVE-2015-0286)

  - A flaw exists in the ASN1_item_ex_d2i() function due to     a failure to reinitialize 'CHOICE' and 'ADB' data     structures when reusing a structure in ASN.1 parsing.
    This allows a remote attacker to cause an invalid write     operation and memory corruption, resulting in a denial     of service. (CVE-2015-0287)

  - A NULL pointer dereference flaw exists in the     X509_to_X509_REQ() function due to improper processing     of certificate keys. This allows a remote attacker, via     a crafted X.509 certificate, to cause a denial of     service. (CVE-2015-0288)

  - A NULL pointer dereference flaw exists in the PKCS#7     parsing code due to incorrect handling of missing outer     ContentInfo. This allows a remote attacker, using an     application that processes arbitrary PKCS#7 data and     providing malformed data with ASN.1 encoding, to cause     a denial of service. (CVE-2015-0289)

  - A flaw exists with the 'multiblock' feature in the     ssl3_write_bytes() function due to improper handling of     certain non-blocking I/O cases. This allows a remote     attacker to cause failed connections or a segmentation     fault, resulting in a denial of service. (CVE-2015-0290)

  - A NULL pointer dereference flaw exists when handling     clients attempting to renegotiate using an invalid     signature algorithm extension. A remote attacker can     exploit this to cause a denial of service.
    (CVE-2015-0291)

  - An integer underflow condition exists in the     EVP_DecodeUpdate() function due to improper validation     of base64 encoded input when decoding. This allows a     remote attacker, using maliciously crafted base64 data,     to cause a segmentation fault or memory corruption,     resulting in a denial of service or possibly the     execution of arbitrary code. (CVE-2015-0292)

  - A flaw exists in servers that both support SSLv2 and     enable export cipher suites due to improper     implementation of SSLv2. A remote attacker can exploit     this, via a crafted CLIENT-MASTER-KEY message, to cause     a denial of service. (CVE-2015-0293)

  - A flaw exists in the ssl3_get_client_key_exchange()     function when client authentication and an ephemeral     Diffie-Hellman ciphersuite are enabled. This allows a     remote attacker, via a ClientKeyExchange message with a     length of zero, to cause a denial of service.
    (CVE-2015-1787)

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

According to its self-reported version number, the Puppet Enterprise application installed on the remote host is version 2.x or 3.x prior to 3.8.0. It is, therefore, affected by the following vulnerabilities :

  - An invalid read error exists in the ASN1_TYPE_cmp()     function due to improperly performed boolean-type     comparisons. A remote attacker can exploit this, via a     crafted X.509 certificate to an endpoint that uses the     certificate-verification feature, to cause an invalid     read operation, resulting in a denial of service.
    (CVE-2015-0286)

  - A flaw exists in the ASN1_item_ex_d2i() function due to     a failure to reinitialize 'CHOICE' and 'ADB' data     structures when reusing a structure in ASN.1 parsing.
    This allows a remote attacker to cause an invalid write     operation and memory corruption, resulting in a denial     of service. (CVE-2015-0287)

  - A NULL pointer dereference flaw exists in the     X509_to_X509_REQ() function due to improper processing     of certificate keys. This allows a remote attacker, via     a crafted X.509 certificate, to cause a denial of     service. (CVE-2015-0288)

  - A NULL pointer dereference flaw exists in the PKCS#7     parsing code due to incorrect handling of missing outer     ContentInfo. This allows a remote attacker, using an     application that processes arbitrary PKCS#7 data and     providing malformed data with ASN.1 encoding, to cause     a denial of service. (CVE-2015-0289)

  - An integer underflow condition exists in the     EVP_DecodeUpdate() function due to improper validation     of base64 encoded input when decoding. This allows a     remote attacker, using maliciously crafted base64 data,     to cause a segmentation fault or memory corruption,     resulting in a denial of service or possibly the     execution of arbitrary code. (CVE-2015-0292)

  - A flaw exists in servers that both support SSLv2 and     enable export cipher suites due to improper     implementation of SSLv2. A remote attacker can exploit     this, via a crafted CLIENT-MASTER-KEY message, to cause     a denial of service. (CVE-2015-0293)

Multiple vulnerabilities has been discovered and corrected in openssl :

Race condition in the ssl3_read_bytes function in s3_pkt.c in OpenSSL through 1.0.1g, when SSL_MODE_RELEASE_BUFFERS is enabled, allows remote attackers to inject data across sessions or cause a denial of service (use-after-free and parsing error) via an SSL connection in a multithreaded environment (CVE-2010-5298).

The Montgomery ladder implementation in OpenSSL through 1.0.0l does not ensure that certain swap operations have a constant-time behavior, which makes it easier for local users to obtain ECDSA nonces via a FLUSH+RELOAD cache side-channel attack (CVE-2014-0076).

The (1) TLS and (2) DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do not properly handle Heartbeat Extension packets, which allows remote attackers to obtain sensitive information from process memory via crafted packets that trigger a buffer over-read, as demonstrated by reading private keys, related to d1_both.c and t1_lib.c, aka the Heartbleed bug (CVE-2014-0160).

The dtls1_reassemble_fragment function in d1_both.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly validate fragment lengths in DTLS ClientHello messages, which allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow and application crash) via a long non-initial fragment (CVE-2014-0195).

The do_ssl3_write function in s3_pkt.c in OpenSSL 1.x through 1.0.1g, when SSL_MODE_RELEASE_BUFFERS is enabled, does not properly manage a buffer pointer during certain recursive calls, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via vectors that trigger an alert condition (CVE-2014-0198).

The dtls1_get_message_fragment function in d1_both.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h allows remote attackers to cause a denial of service (recursion and client crash) via a DTLS hello message in an invalid DTLS handshake (CVE-2014-0221).

OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly restrict processing of ChangeCipherSpec messages, which allows man-in-the-middle attackers to trigger use of a zero-length master key in certain OpenSSL-to-OpenSSL communications, and consequently hijack sessions or obtain sensitive information, via a crafted TLS handshake, aka the CCS Injection vulnerability (CVE-2014-0224).

The ssl3_send_client_key_exchange function in s3_clnt.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h, when an anonymous ECDH cipher suite is used, allows remote attackers to cause a denial of service (NULL pointer dereference and client crash) by triggering a NULL certificate value (CVE-2014-3470).

Memory leak in d1_srtp.c in the DTLS SRTP extension in OpenSSL 1.0.1 before 1.0.1j allows remote attackers to cause a denial of service (memory consumption) via a crafted handshake message (CVE-2014-3513).

The SSL protocol 3.0, as used in OpenSSL through 1.0.1i and other products, uses nondeterministic CBC padding, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, aka the POODLE issue (CVE-2014-3566).

Memory leak in the tls_decrypt_ticket function in t1_lib.c in OpenSSL before 0.9.8zc, 1.0.0 before 1.0.0o, and 1.0.1 before 1.0.1j allows remote attackers to cause a denial of service (memory consumption) via a crafted session ticket that triggers an integrity-check failure (CVE-2014-3567).

The ssl23_get_client_hello function in s23_srvr.c in OpenSSL 0.9.8zc, 1.0.0o, and 1.0.1j does not properly handle attempts to use unsupported protocols, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an unexpected handshake, as demonstrated by an SSLv3 handshake to a no-ssl3 application with certain error handling. NOTE: this issue became relevant after the CVE-2014-3568 fix (CVE-2014-3569).

The BN_sqr implementation in OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k does not properly calculate the square of a BIGNUM value, which might make it easier for remote attackers to defeat cryptographic protection mechanisms via unspecified vectors, related to crypto/bn/asm/mips.pl, crypto/bn/asm/x86_64-gcc.c, and crypto/bn/bn_asm.c (CVE-2014-3570).

OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted DTLS message that is processed with a different read operation for the handshake header than for the handshake body, related to the dtls1_get_record function in d1_pkt.c and the ssl3_read_n function in s3_pkt.c (CVE-2014-3571).

The ssl3_get_key_exchange function in s3_clnt.c in OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k allows remote SSL servers to conduct ECDHE-to-ECDH downgrade attacks and trigger a loss of forward secrecy by omitting the ServerKeyExchange message (CVE-2014-3572).

OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k does not enforce certain constraints on certificate data, which allows remote attackers to defeat a fingerprint-based certificate-blacklist protection mechanism by including crafted data within a certificate's unsigned portion, related to crypto/asn1/a_verify.c, crypto/dsa/dsa_asn1.c, crypto/ecdsa/ecs_vrf.c, and crypto/x509/x_all.c (CVE-2014-8275).

The ssl3_get_key_exchange function in s3_clnt.c in OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k allows remote SSL servers to conduct RSA-to-EXPORT_RSA downgrade attacks and facilitate brute-force decryption by offering a weak ephemeral RSA key in a noncompliant role, related to the FREAK issue. NOTE: the scope of this CVE is only client code based on OpenSSL, not EXPORT_RSA issues associated with servers or other TLS implementations (CVE-2015-0204).

The ssl3_get_cert_verify function in s3_srvr.c in OpenSSL 1.0.0 before 1.0.0p and 1.0.1 before 1.0.1k accepts client authentication with a Diffie-Hellman (DH) certificate without requiring a CertificateVerify message, which allows remote attackers to obtain access without knowledge of a private key via crafted TLS Handshake Protocol traffic to a server that recognizes a Certification Authority with DH support (CVE-2015-0205).

Memory leak in the dtls1_buffer_record function in d1_pkt.c in OpenSSL 1.0.0 before 1.0.0p and 1.0.1 before 1.0.1k allows remote attackers to cause a denial of service (memory consumption) by sending many duplicate records for the next epoch, leading to failure of replay detection (CVE-2015-0206).

Use-after-free vulnerability in the d2i_ECPrivateKey function in crypto/ec/ec_asn1.c in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a might allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via a malformed Elliptic Curve (EC) private-key file that is improperly handled during import (CVE-2015-0209).

The ASN1_TYPE_cmp function in crypto/asn1/a_type.c in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a does not properly perform boolean-type comparisons, which allows remote attackers to cause a denial of service (invalid read operation and application crash) via a crafted X.509 certificate to an endpoint that uses the certificate-verification feature (CVE-2015-0286).

The ASN1_item_ex_d2i function in crypto/asn1/tasn_dec.c in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a does not reinitialize CHOICE and ADB data structures, which might allow attackers to cause a denial of service (invalid write operation and memory corruption) by leveraging an application that relies on ASN.1 structure reuse (CVE-2015-0287).

The X509_to_X509_REQ function in crypto/x509/x509_req.c in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a might allow attackers to cause a denial of service (NULL pointer dereference and application crash) via an invalid certificate key (CVE-2015-0288).

The PKCS#7 implementation in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a does not properly handle a lack of outer ContentInfo, which allows attackers to cause a denial of service (NULL pointer dereference and application crash) by leveraging an application that processes arbitrary PKCS#7 data and providing malformed data with ASN.1 encoding, related to crypto/pkcs7/pk7_doit.c and crypto/pkcs7/pk7_lib.c (CVE-2015-0289).

The SSLv2 implementation in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a allows remote attackers to cause a denial of service (s2_lib.c assertion failure and daemon exit) via a crafted CLIENT-MASTER-KEY message (CVE-2015-0293).
