The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2959-1 advisory.

    Huzaifa Sidhpurwala, Hanno Bck, and David Benjamin discovered that OpenSSL incorrectly handled memory     when decoding ASN.1 structures. A remote attacker could use this issue to cause OpenSSL to crash,     resulting in a denial of service, or possibly execute arbitrary code. (CVE-2016-2108)

    Juraj Somorovsky discovered that OpenSSL incorrectly performed padding when the connection uses the AES     CBC cipher and the server supports AES-NI. A remote attacker could possibly use this issue to perform a     padding oracle attack and decrypt traffic. (CVE-2016-2107)

    Guido Vranken discovered that OpenSSL incorrectly handled large amounts of input data to the     EVP_EncodeUpdate() function. A remote attacker could use this issue to cause OpenSSL to crash, resulting     in a denial of service, or possibly execute arbitrary code. (CVE-2016-2105)

    Guido Vranken discovered that OpenSSL incorrectly handled large amounts of input data to the     EVP_EncryptUpdate() function. A remote attacker could use this issue to cause OpenSSL to crash, resulting     in a denial of service, or possibly execute arbitrary code. (CVE-2016-2106)

    Brian Carpenter discovered that OpenSSL incorrectly handled memory when ASN.1 data is read from a BIO. A     remote attacker could possibly use this issue to cause memory consumption, resulting in a denial of     service. (CVE-2016-2109)

    As a security improvement, this update also modifies OpenSSL behaviour to reject DH key sizes below 1024     bits, preventing a possible downgrade attack.

The remote MiracleLinux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2016-230:03 advisory.

    The OpenSSL toolkit provides support for secure communications between     machines. OpenSSL includes a certificate management tool and shared     libraries which provide various cryptographic algorithms and     protocols.
    Security issues fixed with this release:
    CVE-2016-0799     The fmtstr function in crypto/bio/b_print.c in OpenSSL 1.0.1 before     1.0.1s and 1.0.2 before 1.0.2g improperly calculates string lengths,     which allows remote attackers to cause a denial of service (overflow     and out-of-bounds read) or possibly have unspecified other impact via     a long string, as demonstrated by a large amount of ASN.1 data, a     different vulnerability than CVE-2016-2842.
    CVE-2016-2105     Integer overflow in the EVP_EncodeUpdate function in     crypto/evp/encode.c in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h     allows remote attackers to cause a denial of service (heap memory     corruption) via a large amount of binary data.
    CVE-2016-2106     Integer overflow in the EVP_EncryptUpdate function in     crypto/evp/evp_enc.c in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h     allows remote attackers to cause a denial of service (heap memory     corruption) via a large amount of data.
    CVE-2016-2107     The AES-NI implementation in OpenSSL before 1.0.1t and 1.0.2 before     1.0.2h does not consider memory allocation during a certain padding     check, which allows remote attackers to obtain sensitive cleartext     information via a padding-oracle attack against an AES CBC session,     NOTE: this vulnerability exists because of an incorrect fix for     CVE-2013-0169.
    CVE-2016-2108     The ASN.1 implementation in OpenSSL before 1.0.1o and 1.0.2 before     1.0.2c allows remote attackers to execute arbitrary code or cause a     denial of service (buffer underflow and memory corruption) via an ANY     field in crafted serialized data, aka the negative zero issue.
    CVE-2016-2109     The asn1_d2i_read_bio function in crypto/asn1/a_d2i_fp.c in the ASN.1     BIO implementation in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h     allows remote attackers to cause a denial of service (memory     consumption) via a short invalid encoding.
    CVE-2016-2842     The doapr_outch function in crypto/bio/b_print.c in OpenSSL 1.0.1     before 1.0.1s and 1.0.2 before 1.0.2g does not verify that a certain     memory allocation succeeds, which allows remote attackers to cause a     denial of service (out-of-bounds write or memory consumption) or     possibly have unspecified other impact via a long string, as     demonstrated by a large amount of ASN.1 data, a different     vulnerability than CVE-2016-0799.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

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

The Oracle VM VirtualBox application installed on the remote host is a version prior to 5.0.22. It is, therefore, affected by multiple vulnerabilities in the bundled OpenSSL component :

  - A heap buffer overflow condition exists in the     EVP_EncodeUpdate() function within file     crypto/evp/encode.c that is triggered when handling     a large amount of input data. An unauthenticated, remote     attacker can exploit this to cause a denial of service     condition. (CVE-2016-2105)

  - 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)

  - Flaws exist in the aesni_cbc_hmac_sha1_cipher()     function in file crypto/evp/e_aes_cbc_hmac_sha1.c and     the aesni_cbc_hmac_sha256_cipher() function in file     crypto/evp/e_aes_cbc_hmac_sha256.c that are triggered     when the connection uses an AES-CBC cipher and AES-NI     is supported by the server. A man-in-the-middle attacker     can exploit these to conduct a padding oracle attack,     resulting in the ability to decrypt the network traffic.
    (CVE-2016-2107)

  - 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)

  - An out-of-bounds read error exists in the     X509_NAME_oneline() function within file     crypto/x509/x509_obj.c when handling very long ASN1     strings. An unauthenticated, remote attacker can exploit     this to disclose the contents of stack memory.

Update to latest openssl which fixes various CVE's

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

An update for openssl is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

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

Security Fix(es) :

* A flaw was found in the way OpenSSL encoded certain ASN.1 data structures. An attacker could use this flaw to create a specially crafted certificate which, when verified or re-encoded by OpenSSL, could cause it to crash, or execute arbitrary code using the permissions of the user running an application compiled against the OpenSSL library. (CVE-2016-2108)

* Two integer overflow flaws, leading to buffer overflows, were found in the way the EVP_EncodeUpdate() and EVP_EncryptUpdate() functions of OpenSSL parsed very large amounts of input data. A remote attacker could use these flaws to crash an application using OpenSSL or, possibly, execute arbitrary code with the permissions of the user running that application. (CVE-2016-2105, CVE-2016-2106)

* It was discovered that OpenSSL leaked timing information when decrypting TLS/SSL and DTLS protocol encrypted records when the connection used the AES CBC cipher suite and the server supported AES-NI. A remote attacker could possibly use this flaw to retrieve plain text from encrypted packets by using a TLS/SSL or DTLS server as a padding oracle. (CVE-2016-2107)

* Several flaws were found in the way BIO_*printf functions were implemented in OpenSSL. Applications which passed large amounts of untrusted data through these functions could crash or potentially execute code with the permissions of the user running such an application. (CVE-2016-0799, CVE-2016-2842)

* A denial of service flaw was found in the way OpenSSL parsed certain ASN.1-encoded data from BIO (OpenSSL's I/O abstraction) inputs. An application using OpenSSL that accepts untrusted ASN.1 BIO input could be forced to allocate an excessive amount of data. (CVE-2016-2109)

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

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

Several vulnerabilities were discovered in OpenSSL, a Secure Socket Layer toolkit.

  - CVE-2016-2105     Guido Vranken discovered that an overflow can occur in     the function EVP_EncodeUpdate(), used for Base64     encoding, if an attacker can supply a large amount of     data. This could lead to a heap corruption.

  - CVE-2016-2106     Guido Vranken discovered that an overflow can occur in     the function EVP_EncryptUpdate() if an attacker can     supply a large amount of data. This could lead to a heap     corruption.

  - CVE-2016-2107     Juraj Somorovsky discovered a padding oracle in the AES     CBC cipher implementation based on the AES-NI     instruction set. This could allow an attacker to decrypt     TLS traffic encrypted with one of the cipher suites     based on AES CBC.

  - CVE-2016-2108     David Benjamin from Google discovered that two separate     bugs in the ASN.1 encoder, related to handling of     negative zero integer values and large universal tags,     could lead to an out-of-bounds write.

  - CVE-2016-2109     Brian Carpenter discovered that when ASN.1 data is read     from a BIO using functions such as d2i_CMS_bio(), a     short invalid encoding can cause allocation of large     amounts of memory potentially consuming excessive     resources or exhausting memory.

Additional information about these issues can be found in the OpenSSL security advisory at https://www.openssl.org/news/secadv/20160503.txt

  - A flaw exists in the ssl3_get_key_exchange() function     in file s3_clnt.c when handling a ServerKeyExchange     message for an anonymous DH ciphersuite with the value     of 'p' set to 0. A attacker can exploit this, by causing     a segmentation fault, to crash an application linked     against the library, resulting in a denial of service.
    (CVE-2015-1794)

  - A carry propagating flaw exists in the x86_64 Montgomery     squaring implementation that may cause the BN_mod_exp()     function to produce incorrect results. An attacker can     exploit this to obtain sensitive information regarding     private keys. (CVE-2015-3193)

  - A NULL pointer dereference flaw exists in file     rsa_ameth.c due to improper handling of ASN.1 signatures     that are missing the PSS parameter. A remote attacker     can exploit this to cause the signature verification     routine to crash, resulting in a denial of service     condition. (CVE-2015-3194)

  - A flaw exists in the ASN1_TFLG_COMBINE implementation in     file tasn_dec.c related to handling malformed     X509_ATTRIBUTE structures. A remote attacker can exploit     this to cause a memory leak by triggering a decoding     failure in a PKCS#7 or CMS application, resulting in a     denial of service. (CVE-2015-3195)

  - A race condition exists in s3_clnt.c that is triggered     when PSK identity hints are incorrectly updated in the     parent SSL_CTX structure when they are received by a     multi-threaded client. A remote attacker can exploit     this, via a crafted ServerKeyExchange message, to cause     a double-free memory error, resulting in a denial of     service. (CVE-2015-3196)

  - A cipher algorithm downgrade vulnerability exists due to     a flaw that is triggered when handling cipher     negotiation. A remote attacker can exploit this to     negotiate SSLv2 ciphers and complete SSLv2 handshakes     even if all SSLv2 ciphers have been disabled on the     server. Note that this vulnerability only exists if the     SSL_OP_NO_SSLv2 option has not been disabled.
    (CVE-2015-3197)

  - A key disclosure vulnerability exists due to improper     handling of cache-bank conflicts on the Intel     Sandy-bridge microarchitecture. An attacker can exploit     this to gain access to RSA key information.
    (CVE-2016-0702)

  - A flaw exists in the SSLv2 implementation,     specifically in the get_client_master_key() function     within file s2_srvr.c, due to accepting a nonzero     CLIENT-MASTER-KEY CLEAR-KEY-LENGTH value for an     arbitrary cipher. A man-in-the-middle attacker can     exploit this to determine the MASTER-KEY value and     decrypt TLS ciphertext by leveraging a Bleichenbacher     RSA padding oracle. (CVE-2016-0703)

  - A flaw exists in the SSLv2 oracle protection mechanism,     specifically in the get_client_master_key() function     within file s2_srvr.c, due to incorrectly overwriting     MASTER-KEY bytes during use of export cipher suites.
    A remote attackers can exploit this to more easily     decrypt TLS ciphertext by leveraging a Bleichenbacher     RSA padding oracle. (CVE-2016-0704)

  - A double-free error exists due to improper validation of     user-supplied input when parsing malformed DSA private     keys. A remote attacker can exploit this to corrupt     memory, resulting in a denial of service condition or     the execution of arbitrary code. (CVE-2016-0705)

  - A NULL pointer dereference flaw exists in the     BN_hex2bn() and BN_dec2bn() functions. A remote attacker     can exploit this to trigger a heap corruption, resulting     in the execution of arbitrary code. (CVE-2016-0797)

  - A denial of service vulnerability exists due to improper     handling of invalid usernames. A remote attacker can     exploit this, via a specially crafted username, to leak     300 bytes of memory per connection, exhausting available     memory resources. (CVE-2016-0798)

  - Multiple memory corruption issues exist that allow a     remote attacker to cause a denial of service condition     or the execution of arbitrary code. (CVE-2016-0799)

  - A heap buffer overflow condition exists in the     EVP_EncodeUpdate() function within file     crypto/evp/encode.c that is triggered when handling     a large amount of input data. An unauthenticated, remote     attacker can exploit this to cause a denial of service     condition. (CVE-2016-2105)

  - 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.
