Format string vulnerability in libxml2 before 2.9.4 allows attackers to have unspecified impact via format string specifiers in unknown vectors.

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.

According to its self-reported version, the Nessus Network Monitor running on the remote host is prior to 6.2.2. It is, therefore, affected by multiple vulnerabilities as referenced in the TNS-2023-23 advisory. Several of the third-party components were found to contain vulnerabilities, and updated versions have been made available by the providers. Out of caution and in line with best practice, Tenable has opted to upgrade these components to address the potential impact of the issues. Nessus Network Monitor 6.2.2 updates the following components:

  - c-ares from version 1.10.0 to version 1.19.1.
  - curl from version 7.79.1 to version 8.1.2.
  - libbzip2 from version 1.0.6 to version 1.0.8.
  - libpcre from version 8.42 to version 8.44.
  - libxml2 from version 2.7.7 to version 2.11.1.
