According to its banner, the version of HP System Management Homepage (SMH) hosted on the remote web server is affected by the following vulnerabilities :

  - A denial of service vulnerability exists in the Apache     HTTP Server due to the lack of the mod_reqtimeout     module. An unauthenticated, remote attacker can exploit     this, via a saturation of partial HTTP requests, to     cause a daemon outage. (CVE-2007-6750)

  - A cross-site scripting (XSS) vulnerability exists in     jQuery when using location.hash to select elements. An     unauthenticated, remote attacker can exploit this, via     a specially crafted tag, to inject arbitrary script     code or HTML into the user's browser session.
    (CVE-2011-4969)

  - 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)

  - An out-of-bounds read error exists in cURL and libcurl     within the smb_request_state() function due to improper     bounds checking. An unauthenticated, remote attacker     can exploit this, using a malicious SMB server and     crafted length and offset values, to disclose sensitive     memory information or to cause a denial of service     condition. (CVE-2015-3237)

  - A flaw exists in libxslt in the xsltStylePreCompute()     function within file preproc.c due to a failure to check     if the parent node is an element. An unauthenticated,     remote attacker can exploit this, via a specially     crafted XML file, to cause a denial of service     condition. (CVE-2015-7995)

  - An infinite loop condition exists in the xz_decomp()     function within file xzlib.c when handling xz compressed     XML content due to a failure to detect compression     errors. An unauthenticated, remote attacker can exploit     this, via specially crafted XML data, to cause a denial     of service condition. (CVE-2015-8035)

  - 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)

  - An out-of-bounds read error exists in the fmtstr()     function within file crypto/bio/b_print.c when printing     very long strings due to a failure to properly calculate     string lengths. An unauthenticated, remote attacker can     exploit this, via a long string, to cause a denial of     service condition, as demonstrated by a large amount of     ASN.1 data. (CVE-2016-0799)

  - An unspecified flaw exists that allows a local attacker     to impact the confidentiality and integrity of the     system. No other details are available. (CVE-2016-2015)

  - A flaw exists in the doapr_outch() function within file     crypto/bio/b_print.c due to a failure to verify that a     certain memory allocation succeeds. An unauthenticated,     remote attacker can exploit this, via a long string,     to cause a denial of service condition, as demonstrated     by a large amount of ASN.1 data. (CVE-2016-2842)

The version of Oracle Secure Global Desktop installed on the remote host is 4.63, 4.71, or 5.2 and is missing a security patch from the July 2016 Critical Patch Update (CPU). It is, therefore, affected by the following vulnerabilities :

  - An integer overflow condition exists in the X Server     subcomponent in the read_packet() function due to     improper validation of user-supplied input when     calculating the amount of memory required to handle     returned data. A remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. Note that this vulnerability only     affects versions 4.71 and 5.2. (CVE-2013-2064)

  - A carry propagating flaw exists in the OpenSSL     subcomponent 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 the OpenSSL     subcomponent in file rsa_ameth.c when handling ASN.1     signatures that use the RSA PSS algorithm but are     missing a mask generation function parameter. A remote     attacker can exploit this to cause the signature     verification routine to crash, leading to a denial of     service. (CVE-2015-3194)

  - A key disclosure vulnerability exists in the OpenSSL     subcomponent 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 NULL pointer dereference flaw exists in the OpenSSL     subcomponent 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)

  - Multiple memory corruption issues exist in the OpenSSL     subcomponent 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 OpenSSL     subcomponent 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)

  - Multiple flaws exist in the OpenSSL subcomponent 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)

  - An unspecified flaw exists in the OpenSSL subcomponent     that allows a remote attacker to execute arbitrary     code. (CVE-2016-3613)

The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2016-3558 advisory.

    - fix CVE-2016-2105 - possible overflow in base64 encoding
    - fix CVE-2016-2106 - possible overflow in EVP_EncryptUpdate()
    - fix CVE-2016-2107 - padding oracle in stitched AES-NI CBC-MAC
    - fix CVE-2016-2108 - memory corruption in ASN.1 encoder
    - fix CVE-2016-2109 - possible DoS when reading ASN.1 data from BIO

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.

Versions of OpenSSL prior to 1.0.1s, or 1.0.2g are unpatched for the following vulnerabilities :

 - A flaw exists in the 'SRP_VBASE_get_by_user' method in the SRP Server 'apps/s_server.c' that is triggered when handling invalid usernames. With a specially crafted username, a remote attacker can cause the service to leak 300 bytes of memory per connection, exhausting available memory resources.(
 - A flaw exists in the 'doapr_outch()' function in 'crypto/bio/b_print.c' that is triggered when failing to allocate memory, as the function's return value has no way to signal this error to a calling function. This may allow a context-dependent attacker to corrupt memory and crash a process linked against the library or potentially execute arbitrary code.
 - An out-of-bounds read flaw exists in the 'fmtstr()' function in 'crypto/bio/b_print.c' that is triggered when printing very long strings. This may allow a context-dependent attacker to crash a process linked against the library or to disclose memory contents.
 - A NULL pointer dereference flaw exists in the 'BN_hex2bn()' and 'BN_dec2bn()' functions in 'crypto/bn/bn_print.c'. This may allow a context-dependent attacker to trigger a heap corruption, potentially allowing the execution of arbitrary code.
 - SSLv2 contains a flaw in its implementation, allowing for a cross-protocol Bleichenbacher padding oracle attack (an adaptive chosen-ciphertext attack). Such an attack may allow a man-in-the-middle attacker to decrypt intercepted TLS connections via a series of specially crafted connections to an SSLv2 server that uses the same private key. The monitored connections required to conduct this attack can use any version of the SSL or TLS protocols, including TLS 1.2, as long as they all use the same RSA key exchange method. With each connection, the server response will vary enough so as to leak information to the attacker about the secret keys in use for the victim TLS connection. This information can in turn be used to eventually decrypt the entire TLS connection and gain access to all plaintext traffic between the victim and server.
 - A double-free flaw exists that is triggered as user-supplied input is not properly validated when parsing malformed DSA private keys. This may allow an attacker to corrupt memory to cause a denial of service or potentially execute arbitrary code.
 - A side-channel attack exists that is triggered during the handling of the cache-bank conflicts on the Intel Sandy-bridge microarchitecture. This may allow an attacker to gain access to RSA key information.
 - A flaw exists in 's2_srvr.c' that is triggered as it does not properly enforce that the 'clear-key-length' is 0 for non-export ciphers. This may allow an attacker to displace encrypted-key bytes if clear-key bytes are present for these ciphers, which can allow the attacker to gain access to SSLv2 master-key information.
 - A flaw exists in 's2_srvr.c' that is triggered when the incorrect bytes in the master-key are overwritten during the application of Bleichenbacher protection mechanisms for export cipher suites. This may allow an attacker to potentially execute more efficient variants of the DROWN attack.

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.
