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

    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-2025-49794)

    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.(CVE-2025-49796)

    A flaw was found in the interactive shell of the xmllint command-line tool, used for parsing XML files.
    When a user inputs an overly long command, the program does not check the input size properly, which can     cause it to crash. This issue might allow attackers to run harmful code in rare configurations without     modern protections.(CVE-2025-6170)

    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-2025-6021)

The version of AOS installed on the remote host is prior to 6.10.1.9. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-6.10.1.9 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)

  - setuptools is a package that allows users to download, build, install, upgrade, and uninstall Python     packages. A path traversal vulnerability in `PackageIndex` is present in setuptools prior to version     78.1.1. An attacker would be allowed to write files to arbitrary locations on the filesystem with the     permissions of the process running the Python code, which could escalate to remote code execution     depending on the context. Version 78.1.1 fixes the issue. (CVE-2025-47273)

  - 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.
