"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)");
