The remote host is affected by the vulnerability described in GLSA-201701-37 (libxml2: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in libxml2. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user or automated system to process a       specially crafted XML document, possibly resulting in execution of       arbitrary code with the privileges of the process or a Denial of Service       condition.
  Workaround :

    There is no known workaround at this time.

  - Libxml violates the zlib interface and crashes

A denial of service flaw was found in the way the libxml2 library parsed certain XML files. An attacker could provide a specially crafted XML file that, when parsed by an application using libxml2, could cause that application to use an excessive amount of memory.

The xmlParseConditionalSections function in parser.c in libxml2 does not properly skip intermediary entities when it stops parsing invalid input, which allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) via crafted XML data, a different vulnerability than CVE-2015-7941 .

libxml2 2.9.2 does not properly stop parsing invalid input, which allows context-dependent attackers to cause a denial of service (out-of-bounds read and libxml2 crash) via crafted XML data to the (1) xmlParseEntityDecl or (2) xmlParseConditionalSections function in parser.c, as demonstrated by non-terminated entities.

A heap-based buffer overflow vulnerability was found in xmlDictComputeFastQKey in dict.c.

A heap-based buffer overflow read in xmlParseMisc was found.

A heap-based buffer overflow was found in xmlGROW allowing the attacker to read the memory out of bounds.

A buffer overread in xmlNextChar was found, causing segmentation fault when compiled with ASAN.

Heap-based buffer overflow was found in xmlParseXmlDecl. When conversion failure happens, parser continues to extract more errors which may lead to unexpected behaviour.

Stack-based buffer overread vulnerability with HTML parser in push mode in xmlSAX2TextNode causing segmentation fault when compiled with ASAN.

A vulnerability in libxml2 was found causing DoS by exhausting CPU when parsing specially crafted XML document.

An out-of-bounds heap read in xmlParseXMLDecl happens when a file containing unfinished xml declaration.

A denial of service flaw was found in libxml2. A remote attacker could provide a specially crafted XML or HTML file that, when processed by an application using libxml2, would cause that application to leak potentially sensitive information.(CVE-2015-8242)

A denial of service flaw was found in libxml2. A remote attacker could provide a specially crafted XML or HTML file that, when processed by an application using libxml2, would cause that application to use an excessive amount of CPU.(CVE-2015-5312)

A heap-based buffer overflow flaw was found in the way libxml2 parsed certain crafted XML input. A remote attacker could provide a specially crafted XML file that, when opened in an application linked against libxml2, would cause the application to crash causing a denial of service.(CVE-2015-7942)

It was discovered that libxml2 could access out-of-bounds memory when parsing unclosed HTML comments. A remote attacker could provide a specially crafted XML file that, when processed by an application linked against libxml2, could cause the application to disclose heap memory contents.(CVE-2015-8710)

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.

  - libpcre from version 8.42 to version 8.44.
  - libxml2 from version 2.7.7 to version 2.11.1.
  - libxslt from version 1.1.26 to version 1.1.37.
  - libxmlsec from version 1.2.18 to version 1.2.37.
  - sqlite from version 3.27.2 to version 3.40.1.
  - jQuery Cookie from version 1.3.1 to version 1.4.1.
  - jQuery UI from version 1.13.0 to version 1.13.2.
