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

    Improper Null Termination, Out-of-bounds Read vulnerability in Apache HTTP Server.This issue affects
    Apache HTTP Server: through 2.4.66.Users are recommended to upgrade to version 2.4.67, which fixes the
    issue.(CVE-2026-34032)

    A flaw was found in the `mod_dav_fs` module of Apache HTTP Server. A WebDAV (Web Distributed Authoring and
    Versioning) content author could exploit a path handling issue to directly manipulate trusted DAV property
    databases. This manipulation could potentially lead to child process crashes, resulting in a Denial of
    Service (DoS).(CVE-2026-42535)

    Out-of-bounds Read vulnerability in mod_proxy_ajp of Apache HTTP Server.This issue affects Apache HTTP
    Server: through 2.4.66.Users are recommended to upgrade to version 2.4.67, which fixes the
    issue.(CVE-2026-33857)

    Buffer Over-read vulnerability in Apache HTTP Server.This issue affects Apache HTTP Server: through
    2.4.66.Users are recommended to upgrade to version 2.4.67, which fixes the issue.(CVE-2026-34059)

    Heap-based Buffer Overflow vulnerability in Apache HTTP Server with mod_xml2enc, xml2StartParse, and
    untrusted content This issue affects Apache HTTP Server: from 2.4.0 through 2.4.67.Users are recommended
    to upgrade to version 2.4.68, which fixes the issue.(CVE-2026-42536)

    Buffer Over-read vulnerability in Apache HTTP Server via outbound OCSP requests to an attacker controlled
    OCSP server This issue affects Apache HTTP Server: from 2.4.0 through 2.4.67.Users are recommended to
    upgrade to version 2.4.68, which fixes the issue.(CVE-2026-44185)

    Buffer Underwrite vulnerability in Apache HTTP Server on crafted regular expressions in the
    configuration.This issue affects Apache HTTP Server: from 2.4.0 through 2.4.67.Users are recommended to
    upgrade to version 2.4.68, which fixes the issue.(CVE-2026-44631)

    Heap-based Buffer Overflow vulnerability in mod_proxy_ajp of Apache HTTP Server.If mod_proxy_ajp connects
    to a malicious AJP server this AJP server can send a malicious AJP message back to mod_proxy_ajp and cause
    it to write 4 attacker controlled bytes after the end of a heap based buffer.This issue affects Apache
    HTTP Server: through 2.4.66.Users are recommended to upgrade to version 2.4.67, which fixes the
    issue.(CVE-2026-28780)

    HTTP response splitting vulnerability in multiple Apache HTTP Server modules with untrusted or compromised
    backend servers.This issue affects Apache HTTP Server: from through 2.4.66.Users are recommended to
    upgrade to version 2.4.67, which fixes the issue.(CVE-2026-33523)

    A NULL pointer dereference in mod_dav_lock in Apache HTTP Server 2.4.66 and earlier may allow an attacker
    to crash the server with a malicious request.mod_dav_lock is not used internally by mod_dav or
    mod_dav_fs.The only known use-case for mod_dav_lock was mod_dav_svn from Apache Subversion earlier than
    version 1.2.0.Users are recommended to upgrade to version 2.4.66, which fixes this issue, or remove
    mod_dav_lock.(CVE-2026-29169)

    Improper Privilege Management vulnerability in Apache HTTP Server 2.4.67 and earlier allows local
    .htaccess authors to read files with the privileges of the httpd user.This issue affects Apache HTTP
    Server: from through 2.4.67.Users are recommended to upgrade to version 2.4.68, which fixes the
    issue.(CVE-2026-44119)

    A cross-site scripting vulnerability exists in mod_proxy_ftp's HTML directory list generation in Apache
    HTTP Server 2.4.67 and earlier when listing FTP directory contents either via forward or reverse proxy
    configuration.Users are recommended to upgrade to version 2.4.68, which fixes this issue.(CVE-2026-29170)

    Heap-based Buffer Overflow vulnerability in Apache HTTP Server with malicious backend servers and
    ProxyPassReverseCookie* This issue affects Apache HTTP Server: from 2.4.0 through 2.4.67.Users are
    recommended to upgrade to version 2.4.68, which fixes the issue.(CVE-2026-34356)

    A timing attack against mod_auth_digest in Apache HTTP Server 2.4.66 allows a bypass of Digest
    authentication by a remote attacker.Users are recommended to upgrade to version 2.4.67, which fixes this
    issue.(CVE-2026-33006)

    Out-of-bounds Read vulnerability in Apache HTTP Server with mod_headers and mod_mime and multiple response
    languages.This issue affects Apache HTTP Server: from 2.4.0 through 2.4.67.(CVE-2026-43951)

    Loop with Unreachable Exit Condition ('Infinite Loop') vulnerability in the mod_proxy_ftp module in Apache
    HTTP Server with an attacker controlled backend FTP server.This issue affects undefined: from 2.4.0
    through 2.4.67.Users are recommended to upgrade to version 2.4.68, which fixes the issue.(CVE-2026-44186)

    An escalation of privilege bug in various modules in Apache HTTP 2.4.66 and earlier allows local .htaccess
    authors to read files with the privileges of the httpd user.Users are recommended to upgrade to version
    2.4.67, which fixes this issue.(CVE-2026-24072)

    Allocation of Resources Without Limits or Throttling vulnerability in Apache HTTP Server's   mod_md via
    OCSP response data.This issue affects Apache HTTP Server: from 2.4.30 through 2.4.66.Users are recommended
    to upgrade to version 2.4.67, which fixes the issue.(CVE-2026-29168)

    A NULL pointer dereference in the mod_authn_socache in Apache HTTP Server 2.4.66 and earlier allows an
    unauthenticated remote user to crash a child process in a caching forward proxy configuration.Users are
    recommended to upgrade to version 2.4.67, which fixes this issue.(CVE-2026-33007)
