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

    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 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 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)

    Multiple security issues were found in libxml2, the GNOME XML library,     which could yield to denial of service or potentially arbitrary code     execution.

    CVE-2024-34459

        Zhineng Zhong discovered that formatting error messages with `xmllint
        --htmlout` could result in a buffer over-read.

    CVE-2025-6021

        Ahmed Lekssays discovered an integer overflow issue in         `xmlBuildQName()` which could result in memory corruption or a         denial of service when processing crafted input.

    CVE-2025-6170

        Ahmed Lekssays discovered a stack-based buffer overflow issue in the         command-parsing logic of the interactive shell in xmllint.

    CVE-2025-49794

        Nikita Sveshnikov discovered a heap use-after-free issue in the         schematron.  When processing XPath expressions in Schematron schema         elements `<sch:name path=/>`, a pointer to freed memory is         returned and then accessed, leading to undefined behavior or         potential crashes.

    CVE-2025-49796

        Nikita Sveshnikov discovered a type confusion issue in the         schematron.  Processing `sch:name` elements and accessing namespace         information may lead to leading to memory corruption or undefined         behavior.

    For Debian 11 bullseye, these problems have been fixed in version     2.9.10+dfsg-6.7+deb11u8.

    We recommend that you upgrade your libxml2 packages.
