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

    A partial fix for CVE-2024-39884 in the core of Apache HTTP Server 2.4.61 ignores some use of the legacy
    content-type based configuration of handlers. 'AddType' and similar configuration, under some
    circumstances where files are requested indirectly, result in source code disclosure of local content. For
    example, PHP scripts may be served instead of interpreted.Users are recommended to upgrade to version
    2.4.62, which fixes this issue.(CVE-2024-40725)

    In some mod_ssl configurations on Apache HTTP Server versions through to 2.4.63, an HTTP desynchronisation
    attack allows a man-in-the-middle attacker to hijack an HTTP session via a TLS upgrade.Only configurations
    using 'SSLEngine optional' to enable TLS upgrades are affected. Users are recommended to upgrade to
    version 2.4.64, which removes support for TLS upgrade.(CVE-2025-49812)

    In some mod_ssl configurations on Apache HTTP Server 2.4.35 through to 2.4.63, an access control bypass by
    trusted clients is possible using TLS 1.3 session resumption.Configurations are affected when mod_ssl is
    configured for multiple virtual hosts, with each restricted to a different set of trusted client
    certificates (for example with a different SSLCACertificateFile/Path setting). In such a case, a client
    trusted to access one virtual host may be able to access another virtual host, if SSLStrictSNIVHostCheck
    is not enabled in either virtual host.(CVE-2025-23048)

    Insufficient escaping of user-supplied data in mod_ssl in Apache HTTP Server 2.4.63 and earlier allows an
    untrusted SSL/TLS client to insert escape characters into log files in some configurations.In a logging
    configuration where CustomLog is used with '%{varname}x' or '%{varname}c' to log variables provided by
    mod_ssl such as SSL_TLS_SNI, no escaping is performed by either mod_log_config or mod_ssl and unsanitized
    data provided by the client may appear in log files.(CVE-2024-47252)

    SSRF in Apache HTTP Server with mod_proxy loaded allows an attacker to send outbound proxy requests to a
    URL controlled by the attacker. Requires an unlikely configuration where mod_headers is configured to
    modify the Content-Type request or response header with a value provided in the HTTP request.Users are
    recommended to upgrade to version 2.4.64 which fixes this issue.(CVE-2024-43204)

    HTTP response splitting in the core of Apache HTTP Server allows an attacker who can manipulate the
    Content-Type response headers of applications hosted or proxied by the server can split the HTTP
    response.This vulnerability was described as CVE-2023-38709 but the patch included in Apache HTTP Server
    2.4.59 did not address the issue.Users are recommended to upgrade to version 2.4.64, which fixes this
    issue.(CVE-2024-42516)

    Apache HTTP Server 2.4.65 and earlier with Server Side Includes (SSI) enabled and mod_cgid (but not
    mod_cgi) passes the shell-escaped query string to #exec cmd='...' directives.This issue affects Apache
    HTTP Server before 2.4.66.Users are recommended to upgrade to version 2.4.66, which fixes the
    issue.(CVE-2025-58098)

    Improper Neutralization of Escape, Meta, or Control Sequences vulnerability in Apache HTTP Server through
    environment variables set via the Apache configuration unexpectedly superseding variables calculated by
    the server for CGI programs.This issue affects Apache HTTP Server from 2.4.0 through 2.4.65.Users are
    recommended to upgrade to version 2.4.66 which fixes the issue.(CVE-2025-65082)

    mod_userdir+suexec bypass via AllowOverride FileInfo vulnerability in Apache HTTP Server. Users with
    access to use the RequestHeader directive in htaccess can cause some CGI scripts to run under an
    unexpected userid.This issue affects Apache HTTP Server: from 2.4.7 through 2.4.65.Users are recommended
    to upgrade to version 2.4.66, which fixes the issue.(CVE-2025-66200)

    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)

    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)

    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)

    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)

    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)

    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)

    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)

    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)
