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

  - Issue summary: A timing side-channel which could potentially allow recovering the private key exists in
    the ECDSA signature computation. Impact summary: A timing side-channel in ECDSA signature computations
    could allow recovering the private key by an attacker. However, measuring the timing would require either
    local access to the signing application or a very fast network connection with low latency. There is a
    timing signal of around 300 nanoseconds when the top word of the inverted ECDSA nonce value is zero. This
    can happen with significant probability only for some of the supported elliptic curves. In particular the
    NIST P-521 curve is affected. To be able to measure this leak, the attacker process must either be located
    in the same physical computer or must have a very fast network connection with low latency. For that
    reason the severity of this vulnerability is Low. The FIPS modules in 3.4, 3.3, 3.2, 3.1 and 3.0 are
    affected by this issue. (CVE-2024-13176)

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