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

    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)

    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)

    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 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)

    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)
