The version of lasso installed on the remote host is prior to 2.9.0-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2025-3077 advisory.

    A denial of service vulnerability exists in the lasso_provider_verify_saml_signature functionality of     Entr'ouvert Lasso 2.5.1. A specially crafted SAML response can lead to a denial of service. An     attacker can send a malformed SAML response to trigger this vulnerability. (CVE-2025-46404)

    A denial of service vulnerability exists in the g_assert_not_reached functionality of Entr'ouvert     Lasso 2.5.1 and 2.8.2. A specially crafted SAML assertion response can lead to a denial of service. An     attacker can send a malformed SAML response to trigger this vulnerability. (CVE-2025-46705)

    A denial of service vulnerability exists in the lasso_node_init_from_message_with_format functionality of     Entr'ouvert Lasso 2.5.1. A specially crafted SAML response can lead to a memory depletion, resulting     in denial of service. An attacker can send a malformed SAML response to trigger this vulnerability.
    (CVE-2025-46784)

    A type confusion vulnerability exists in the lasso_node_impl_init_from_xml functionality of     Entr'ouvert Lasso 2.5.1 and 2.8.2. A specially crafted SAML response can lead to an arbitrary code     execution. An attacker can send a malformed SAML response to trigger this vulnerability. (CVE-2025-47151)
