    Package : libapache2-mod-auth-openidc
    CVE ID : CVE-2025-3891

    A vulnerability has been discovered in mod_auth_openidc, an OpenID
    Certified authentication and authorization module for the Apache HTTP
    server that implements the OpenID Connect Relying Party functionality:

    An unauthenticated attacker could crash the Apache httpd process by
    sending a POST request without a Content-Type header if the
    'OIDCPreservePost' directive is enabled, resulting in denial of
    service.

    For the stable distribution (bookworm), this problem has been fixed in
    version 2.4.12.3-2+deb12u4.

    We recommend that you upgrade your libapache2-mod-auth-openidc packages.

    For the detailed security status of libapache2-mod-auth-openidc please refer to its security tracker page at: https://security-tracker.debian.org/tracker/libapache2-mod-auth-openidc
