There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - Mbed TLS before 2.28.10 and 3.x before 3.6.3, on the client side, accepts servers that have trusted
    certificates for arbitrary hostnames unless the TLS client application calls mbedtls_ssl_set_hostname.
    (CVE-2025-27809)

  - Mbed TLS before 2.28.10 and 3.x before 3.6.3, in some cases of failed memory allocation or hardware
    errors, uses uninitialized stack memory to compose the TLS Finished message, potentially leading to
    authentication bypasses such as replays. (CVE-2025-27810)

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - An issue was discovered in Mbed TLS before 2.28.9 and 3.x before 3.6.1, in which the user-selected
    algorithm is not used. Unlike previously documented, enabling MBEDTLS_PSA_HMAC_DRBG_MD_TYPE does not cause
    the PSA subsystem to use HMAC_DRBG: it uses HMAC_DRBG only when MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG and
    MBEDTLS_CTR_DRBG_C are disabled. (CVE-2024-45157)

  - Mbed TLS before 2.28.10 and 3.x before 3.6.3, on the client side, accepts servers that have trusted
    certificates for arbitrary hostnames unless the TLS client application calls mbedtls_ssl_set_hostname.
    (CVE-2025-27809)

  - Mbed TLS before 2.28.10 and 3.x before 3.6.3, in some cases of failed memory allocation or hardware
    errors, uses uninitialized stack memory to compose the TLS Finished message, potentially leading to
    authentication bypasses such as replays. (CVE-2025-27810)

Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。

  - 2.28.10 之前的 [] 和 3.x 之前的 3.6.3用戶端的 Mbed TLS除非 TLS 用戶端應用程式呼叫 mbedtls_ssl_set_hostname否則會接受具有任意主機名稱之受信任憑證的伺服器。
    (CVE-2025-27809)

請注意，Nessus 依賴供應商報告的套件存在。

Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - 低于 2.28.10 和 3.x 之前的 3.6.3的 Mbed TLS 在客户端接受具有任意主机名的受信任证书的服务器除非 TLS 客户端应用程序调用 mbedtls_ssl_set_hostname。
    (CVE-2025-27809)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

Linux/Unix ホストには、ベンダーが提供するパッチが利用できない脆弱性の影響を受ける複数のパッケージがインストールされています。

  - 2.28.10 より前の Mbed TLS および 3.x ] より前の 3.6.3] は、クライアントサイドで、TLS クライアントアプリケーションが mbedtls_ssl_set_hostname を呼び出さない限り、任意のホスト名に対して信頼できる証明書を持つサーバーを受け入れます。
    (CVE-2025-27809)

Nessus は、ベンダーによって報告されたパッケージの存在に依存していることに注意してください。

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Mbed TLS before 2.28.10 and 3.x before 3.6.3, on the client side, accepts servers that have trusted     certificates for arbitrary hostnames unless the TLS client application calls mbedtls_ssl_set_hostname.
    (CVE-2025-27809)

Note that Nessus relies on the presence of the package as reported by the vendor.

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-2025:0337 advisory.

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

    CVE-2025-27810:
    Mbed TLS before 2.28.10 and 3.x before 3.6.3, in some cases of failed memory allocation or hardware     errors, uses uninitialized stack memory to compose the TLS Finished message, potentially leading to     authentication bypasses such as replays.

    CVE-2025-27809:
    Mbed TLS before 2.28.10 and 3.x before 3.6.3, on the client side, accepts servers that have trusted     certificates for arbitrary hostnames unless the TLS client application calls mbedtls_ssl_set_hostname.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

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