Vulnerability from osv_openeuler
The package is a implements the Liberty Alliance Single Sign On standards library, includeing the SAML2 and SAML specifications. it provides bindings for multiple languages.and allows to handle the whole life-cycle of SAML based Federations.
Security Fix(es):
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 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)
