According to the versions of the xulrunner package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Expat, when used in a parser that has not called     XML_SetHashSalt or passed it a seed of 0, makes it     easier for context-dependent attackers to defeat     cryptographic protection mechanisms via vectors     involving use of the srand function.(CVE-2012-6702)

  - The overflow protection in Expat is removed by     compilers with certain optimization settings, which     allows remote attackers to cause a denial of service     (crash) or possibly execute arbitrary code via crafted     XML data. NOTE: this vulnerability exists because of an     incomplete fix for CVE-2015-1283 and     CVE-2015-2716.(CVE-2016-4472)

  - Expat allows context-dependent attackers to cause a     denial of service (crash) or possibly execute arbitrary     code via a malformed input document, which triggers a     buffer overflow.(CVE-2016-0718)

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

The version of Apple iTunes installed on the remote Windows host is prior to 12.6. It is, therefore, affected by multiple vulnerabilities :

  - Multiple vulnerabilities exist in the expat component,     the most severe of which are remote code execution     vulnerabilities. An unauthenticated, remote attacker can     exploit these vulnerabilities to cause a denial of     service condition or the execution of arbitrary code in     the context of the current user. (CVE-2009-3270,     CVE-2009-3560, CVE-2009-3720, CVE-2012-1147,     CVE-2012-1148, CVE-2012-6702, CVE-2015-1283,     CVE-2016-0718, CVE-2016-4472, CVE-2016-5300)

  - Multiple vulnerabilities exist in the SQLite component,     the most severe of which are remote code execution     vulnerabilities. An unauthenticated, remote attacker can     exploit these vulnerabilities by convincing a user to     open a specially crafted file, to cause a denial of     service condition or the execution of arbitrary code in     the context of the current user. (CVE-2013-7443,     CVE-2015-3414, CVE-2015-3415, CVE-2015-3416,     CVE-2015-3717, CVE-2015-6607, CVE-2016-6153)

  - An information disclosure vulnerability exists in the     APNs server component due to client certificates being     transmitted in cleartext. A man-in-the-middle attacker     can exploit this to disclose sensitive information.
    (CVE-2017-2383)

  - A use-after-free error exists in the WebKit component     due to improper handling of RenderBox objects. An     unauthenticated, remote attacker can exploit this to     execute arbitrary code. (CVE-2017-2463)

  - Multiple universal cross-site scripting (XSS)     vulnerabilities exist in the WebKit component due to     improper validation of user-supplied input. An     unauthenticated, remote attacker can exploit these     vulnerabilities, by convincing a user to visit a     specially crafted web page, to execute arbitrary script     code in a user's browser session. (CVE-2017-2479,     CVE-2017-2480, CVE-2017-2493)

  - An integer overflow condition exists in the libxslt     component in the xsltAddTextString() function in     transform.c due to improper validation of user-supplied     input. An unauthenticated, remote attacker can exploit     this to cause an out-of-bounds write, resulting in the     execution of arbitrary code. (CVE-2017-5029)

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