The version of OpenSSL installed on the remote host is prior to 1.0.2zj. It is, therefore, affected by multiple vulnerabilities as referenced in the 1.0.2zj advisory.

  - Issue summary: Processing a maliciously formatted PKCS12 file may lead OpenSSL to crash leading to a     potential Denial of Service attack Impact summary: Applications loading files in the PKCS12 format from     untrusted sources might terminate abruptly. A file in PKCS12 format can contain certificates and keys and     may come from an untrusted source. The PKCS12 specification allows certain fields to be NULL, but OpenSSL     does not correctly check for this case. This can lead to a NULL pointer dereference that results in     OpenSSL crashing. If an application processes PKCS12 files from an untrusted source using the OpenSSL APIs     then that application will be vulnerable to this issue. OpenSSL APIs that are vulnerable to this are:
    PKCS12_parse(), PKCS12_unpack_p7data(), PKCS12_unpack_p7encdata(), PKCS12_unpack_authsafes() and     PKCS12_newpass(). We have also fixed a similar issue in SMIME_write_PKCS7(). However since this function     is related to writing data we do not consider it security significant. The FIPS modules in 3.2, 3.1 and     3.0 are not affected by this issue. (CVE-2024-0727)

  - Issue summary: Generating excessively long X9.42 DH keys or checking excessively long X9.42 DH keys or     parameters may be very slow. Impact summary: Applications that use the functions DH_generate_key() to     generate an X9.42 DH key may experience long delays. Likewise, applications that use DH_check_pub_key(),     DH_check_pub_key_ex() or EVP_PKEY_public_check() to check an X9.42 DH key or X9.42 DH parameters may     experience long delays. Where the key or parameters that are being checked have been obtained from an     untrusted source this may lead to a Denial of Service. While DH_check() performs all the necessary checks     (as of CVE-2023-3817), DH_check_pub_key() doesn't make any of these checks, and is therefore vulnerable     for excessively large P and Q parameters. Likewise, while DH_generate_key() performs a check for an     excessively large P, it doesn't check for an excessively large Q. An application that calls     DH_generate_key() or DH_check_pub_key() and supplies a key or parameters obtained from an untrusted source     could be vulnerable to a Denial of Service attack. DH_generate_key() and DH_check_pub_key() are also     called by a number of other OpenSSL functions. An application calling any of those other functions may     similarly be affected. The other functions affected by this are DH_check_pub_key_ex(),     EVP_PKEY_public_check(), and EVP_PKEY_generate(). Also vulnerable are the OpenSSL pkey command line     application when using the -pubcheck option, as well as the OpenSSL genpkey command line application.
    The OpenSSL SSL/TLS implementation is not affected by this issue. The OpenSSL 3.0 and 3.1 FIPS providers     are not affected by this issue. (CVE-2023-5678)

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