critical Nessus Plugin ID 274695

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-1285 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 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)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'dnf update lasso --releasever 2023.9.20251110' or or 'dnf update --advisory ALAS2023-2025-1285 --releasever 2023.9.20251110' to update your system.
