"The version of Junos OS installed on the remote host is affected by multiple vulnerabilities as referenced in the
JSA73176 advisory.

  - AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimised implementation will not encrypt
    the entirety of the data under some circumstances. This could reveal sixteen bytes of data that was
    preexisting in the memory that wasn't written. In the special case of in place encryption, sixteen bytes
    of the plaintext would be revealed. Since OpenSSL does not support OCB based cipher suites for TLS and
    DTLS, they are both unaffected. Fixed in OpenSSL 3.0.5 (Affected 3.0.0-3.0.4). Fixed in OpenSSL 1.1.1q
    (Affected 1.1.1-1.1.1p). (CVE-2022-2097)

  - The OpenSSL 3.0.4 release introduced a serious bug in the RSA implementation for X86_64 CPUs supporting
    the AVX512IFMA instructions. This issue makes the RSA implementation with 2048 bit private keys incorrect
    on such machines and memory corruption will happen during the computation. As a consequence of the memory
    corruption an attacker may be able to trigger a remote code execution on the machine performing the
    computation. SSL/TLS servers or other servers using 2048 bit RSA private keys running on machines
    supporting AVX512IFMA instructions of the X86_64 architecture are affected by this issue. (CVE-2022-2274)

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