The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2025:0862 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2025-47151:
    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-2025-46705:
    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-2025-46404:
    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.
