An issue was discovered in Mbed TLS 3.6 before 3.6.1. A stack buffer overflow in mbedtls_ecdsa_der_to_raw() and mbedtls_ecdsa_raw_to_der() can occur when the bits parameter is larger than the largest supported curve. In some configurations with PSA disabled, all values of bits are affected. (This never happens in internal library calls, but can affect applications that call these functions directly.)

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

  - An issue was discovered in Mbed TLS 3.6 before 3.6.1. A stack buffer overflow in     mbedtls_ecdsa_der_to_raw() and mbedtls_ecdsa_raw_to_der() can occur when the bits parameter is larger than     the largest supported curve. In some configurations with PSA disabled, all values of bits are affected.
    (This never happens in internal library calls, but can affect applications that call these functions     directly.) (CVE-2024-45158)

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

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)

  - An issue was discovered in Mbed TLS 3.6 before 3.6.1. A stack buffer overflow in
    mbedtls_ecdsa_der_to_raw() and mbedtls_ecdsa_raw_to_der() can occur when the bits parameter is larger than
    the largest supported curve. In some configurations with PSA disabled, all values of bits are affected.
    (This never happens in internal library calls, but can affect applications that call these functions
    directly.) (CVE-2024-45158)

  - An issue was discovered in Mbed TLS 3.x before 3.6.1. With TLS 1.3, when a server enables optional
    authentication of the client, if the client-provided certificate does not have appropriate values in if
    keyUsage or extKeyUsage extensions, then the return value of mbedtls_ssl_get_verify_result() would
    incorrectly have the MBEDTLS_X509_BADCERT_KEY_USAGE and MBEDTLS_X509_BADCERT_KEY_USAGE bits clear. As a
    result, an attacker that had a certificate valid for uses other than TLS client authentication would
    nonetheless be able to use it for TLS client authentication. Only TLS 1.3 servers were affected, and only
    with optional authentication (with required authentication, the handshake would be aborted with a fatal
    alert). (CVE-2024-45159)
