The remote Ubuntu 24.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7264-1 advisory.

    It was discovered that OpenSSL clients incorrectly handled authenticating servers using RFC7250 Raw Public     Keys. In certain cases, the connection will not abort as expected, possibly causing the communication to     be intercepted. (CVE-2024-12797)

    George Pantelakis and Alicja Kario discovered that OpenSSL had a timing side-channel when performing ECDSA     signature computations. A remote attacker could possibly use this issue to recover private data.
    (CVE-2024-13176)

    It was discovered that OpenSSL incorrectly handled certain memory operations when using low-level GF(2^m)     elliptic curve APIs with untrusted explicit values for the field polynomial. When being used in this     uncommon fashion, a remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial     of service, or possibly execute arbitrary code.

It is, therefore, affected by a vulnerability as referenced in the ALAS2-2025-2750 advisory.

    Issue summary: A timing side-channel which could potentially allow recoveringthe private key exists in the     ECDSA signature computation.

    Impact summary: A timing side-channel in ECDSA signature computationscould allow recovering the private     key by an attacker. However, measuringthe timing would require either local access to the signing     application ora very fast network connection with low latency.

    There is a timing signal of around 300 nanoseconds when the top word ofthe inverted ECDSA nonce value is     zero. This can happen with significantprobability only for some of the supported elliptic curves. In     particularthe NIST P-521 curve is affected. To be able to measure this leak, the attackerprocess must     either be located in the same physical computer or musthave a very fast network connection with low     latency. For that reasonthe severity of this vulnerability is Low. (CVE-2024-13176)

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. (CVE-2024-13176)

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