The remote host is affected by the vulnerability described in GLSA-201710-24 (Chromium, Google Chrome: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Chromium and Google       Chrome. Please review the referenced CVE identifiers and Google Chrome       Releases for details.
  Impact :

    A remote attacker could possibly execute arbitrary code with the       privileges of the process, cause a Denial of Service condition, bypass       content security controls, or conduct URL spoofing.
  Workaround :

    There is no known workaround at this time.

According to the versions of the libxml2 packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - An integer overflow in xmlmemory.c in libxml2 before     2.9.5, as used in Google Chrome prior to 62.0.3202.62     and other products, allowed a remote attacker to     potentially exploit heap corruption via a crafted XML     file.(CVE-2017-5130)

  - libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a     heap-based buffer over-read in the     xmlDictComputeFastKey function in dict.c. This     vulnerability causes programs that use libxml2, such as     PHP, to crash. (CVE-2017-9049)

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 Oracle HTTP Server installed on the remote host is affected by the following vulnerabilities as referenced in the April 2020 CPU advisory:

  - An integer overflow in xmlmemory.c in libxml2 before 2.9.5, as used in Oracle HTTP Server's Web Listener     component, allows a remote attacker to potentially exploit heap corruption via a crafted XML file.
    (CVE-2017-5130)

  - An easily exploitable vulnerability in Oracle HTTP Server's Web Listener component affecting the supported     version 11.1.1.9.0. An unauthenticated, remote attacker with network access via HTTP can exploit this to     compromise Oracle HTTP Server, resulting in unauthorized update, insert or delete access to some of Oracle     HTTP Server accessible data as well as unauthorized read access to a subset of Oracle HTTP Server     accessible data. (CVE-2020-2952)

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

The version of Apple iOS running on the mobile device is prior to 11.0.1. It is, therefore, affected by multiple vulnerabilities as described in the HT208143 security advisory.
