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

    In libxml2 before 2.13.8 and 2.14.x before 2.14.2, out-of-bounds memory access can occur in the Python API     (Python bindings) because of an incorrect return value. This occurs in xmlPythonFileRead and     xmlPythonFileReadRaw because of a difference between bytes and characters.(CVE-2025-32414)

    In libxml2 before 2.13.8 and 2.14.x before 2.14.2, xmlSchemaIDCFillNodeTables in xmlschemas.c has a heap-     based buffer under-read. To exploit this, a crafted XML document must be validated against an XML schema     with certain identity constraints, or a crafted XML schema must be used.(CVE-2025-32415)

Tenable has extracted the preceding description block directly from the EulerOS libxml2 security advisory.

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

The version of AHV installed on the remote host is prior to 20230302.103053. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20230302.103053 advisory.

  - inftrees.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact by leveraging     improper pointer arithmetic. (CVE-2016-9840)

  - xsltGetInheritedNsList in libxslt before 1.1.43 has a use-after-free issue related to exclusion of result     prefixes. (CVE-2024-55549)

  - numbers.c in libxslt before 1.1.43 has a use-after-free because, in nested XPath evaluations, an XPath     context node can be modified but never restored. This is related to xsltNumberFormatGetValue,     xsltEvalXPathPredicate, xsltEvalXPathStringNs, and xsltComputeSortResultInternal. (CVE-2025-24855)

  - An out of bounds write exists in FreeType versions 2.13.0 and below (newer versions of FreeType are not     vulnerable) when attempting to parse font subglyph structures related to TrueType GX and variable font     files. The vulnerable code assigns a signed short value to an unsigned long and then adds a static value     causing it to wrap around and allocate too small of a heap buffer. The code then writes up to 6 signed     long integers out of bounds relative to this buffer. This may result in arbitrary code execution. This     vulnerability may have been exploited in the wild. (CVE-2025-27363)

  - A stack overflow vulnerability exists in the libexpat library due to the way it handles recursive entity     expansion in XML documents. When parsing an XML document with deeply nested entity references, libexpat     can be forced to recurse indefinitely, exhausting the stack space and causing a crash. This issue could     lead to denial of service (DoS) or, in some cases, exploitable memory corruption, depending on the     environment and library usage. (CVE-2024-8176)

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

According to its self-reported version, the Nessus Network Monitor running on the remote host is prior to 6.5.1. It is, therefore, affected by multiple vulnerabilities as referenced in the TNS-2025-10 advisory.

  - In libxml2 before 2.13.8 and 2.14.x before 2.14.2, xmlSchemaIDCFillNodeTables in xmlschemas.c has a     heap-based buffer under-read. To exploit this, a crafted XML document must be validated against an XML     schema with certain identity constraints, or a crafted XML schema must be used. (CVE-2025-32415)

  - When installing Tenable Network Monitor to a non-default location on a Windows host, Tenable Network     Monitor versions prior to 6.5.1 did not enforce secure permissions for sub-directories. This could allow     for local privilege escalation if users had not secured the directories in the non-default installation     location. (CVE-2025-24916)

  - In Tenable Network Monitor versions prior to 6.5.1 on a Windows host, it was found that a     non-administrative user could stage files in a local directory to run arbitrary code with SYSTEM     privileges, potentially leading to local privilege escalation. (CVE-2025-24917)

The version of Tencent Linux installed on the remote TencentOS Server 2 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2025:0786 advisory.

    Package updates are available for TencentOS Server 2 that fix the following vulnerabilities:

    CVE-2025-6021:
    A flaw was found in libxml2's xmlBuildQName function, where integer overflows in buffer size calculations     can lead to a stack-based buffer overflow. This issue can result in memory corruption or a denial of     service when processing crafted input.

    CVE-2025-32414:
    In libxml2 before 2.13.8 and 2.14.x before 2.14.2, out-of-bounds memory access can occur in the Python API     (Python bindings) because of an incorrect return value. This occurs in xmlPythonFileRead and     xmlPythonFileReadRaw because of a difference between bytes and characters.

    CVE-2025-49794:
    A use-after-free vulnerability was found in libxml2. This issue occurs when parsing XPath elements under     certain circumstances when the XML schematron has the <sch:name path=.../> schema elements. This flaw     allows a malicious actor to craft a malicious XML document used as input for libxml, resulting in the     program's crash using libxml or other possible undefined behaviors.

    CVE-2025-49796:
    A vulnerability was found in libxml2. Processing certain sch:name elements from the input XML file can     trigger a memory corruption issue. This flaw allows an attacker to craft a malicious XML input file that     can lead libxml to crash, resulting in a denial of service or other possible undefined behavior due to     sensitive data being corrupted in memory.

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2025:0527 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2025-6021:
    A flaw was found in libxml2's xmlBuildQName function, where integer overflows in buffer size calculations     can lead to a stack-based buffer overflow. This issue can result in memory corruption or a denial of     service when processing crafted input.

    CVE-2025-49795:
    A NULL pointer dereference vulnerability was found in libxml2 when processing XPath XML expressions. This     flaw allows an attacker to craft a malicious XML input to libxml2, leading to a denial of service.

    CVE-2025-49794:
    A use-after-free vulnerability was found in libxml2. This issue occurs when parsing XPath elements under     certain circumstances when the XML schematron has the <sch:name path=.../> schema elements. This flaw     allows a malicious actor to craft a malicious XML document used as input for libxml, resulting in the     program's crash using libxml or other possible undefined behaviors.

    CVE-2025-32415:

The remote NewStart CGSL host, running version MAIN 7.02, has libxml2 packages installed that are affected by multiple vulnerabilities:

  - In libxml2 before 2.13.8 and 2.14.x before 2.14.2, out-of-bounds memory access can occur in the Python API     (Python bindings) because of an incorrect return value. This occurs in xmlPythonFileRead and     xmlPythonFileReadRaw because of a difference between bytes and characters. (CVE-2025-32414)

  - libxml2 through 2.11.5 has a use-after-free that can only occur after a certain memory allocation fails.
    This occurs in xmlUnlinkNode in tree.c. NOTE: the vendor's position is I don't think these issues are     critical enough to warrant a CVE ID ... because an attacker typically can't control when memory     allocations fail. (CVE-2023-45322)

  - An issue was discovered in libxml2 before 2.11.7 and 2.12.x before 2.12.5. When using the XML Reader     interface with DTD validation and XInclude expansion enabled, processing crafted XML documents can lead to     an xmlValidatePopElement use-after-free. (CVE-2024-25062)

  - In libxml2 2.11 before 2.11.9, 2.12 before 2.12.9, and 2.13 before 2.13.3, the SAX parser can produce     events for external entities even if custom SAX handlers try to override entity content (by setting     checked). This makes classic XXE attacks possible. (CVE-2024-40896)

  - libxml2 before 2.12.10 and 2.13.x before 2.13.6 has a use-after-free in xmlSchemaIDCFillNodeTables and     xmlSchemaBubbleIDCNodeTables in xmlschemas.c. To exploit this, a crafted XML document must be validated     against an XML schema with certain identity constraints, or a crafted XML schema must be used.
