The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - libxml2: Use after free via namespace node in XPointer ranges (CVE-2016-4658)

  - libxml2: Missing validation for external entities in xmlParsePEReference (CVE-2017-7375)

  - libxml2 through 2.9.1 does not properly handle external entities expansion unless an application developer     uses the xmlSAX2ResolveEntity or xmlSetExternalEntityLoader function, which allows remote attackers to     cause a denial of service (resource consumption), send HTTP requests to intranet servers, or read     arbitrary files via a crafted XML document, aka an XML External Entity (XXE) issue. NOTE: it could be     argued that because libxml2 already provides the ability to disable external entity expansion, the     responsibility for resolving this issue lies with application developers; according to this argument, this     entry should be REJECTed and each affected application would need its own CVE. (CVE-2013-0339)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

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.
