It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2024-520 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: Checking excessively long invalid RSA public keys may take a long time. Impact summary:
    Applications that use the function EVP_PKEY_public_check() to check RSA public keys may experience long     delays. Where the key that is being checked has been obtained from an untrusted source this may lead to a     Denial of Service. When function EVP_PKEY_public_check() is called on RSA public keys, a computation is     done to confirm that the RSA modulus, n, is composite. For valid RSA keys, n is a product of two or more     large primes and this computation completes quickly. However, if n is an overly large prime, then this     computation would take a long time. An application that calls EVP_PKEY_public_check() and supplies an RSA     key obtained from an untrusted source could be vulnerable to a Denial of Service attack. The function     EVP_PKEY_public_check() is not called from other OpenSSL functions however it is called from the OpenSSL     pkey command line application. For that reason that application is also vulnerable if used with the     '-pubin' and '-check' options on untrusted data. The OpenSSL SSL/TLS implementation is not affected by     this issue. The OpenSSL 3.0 and 3.1 FIPS providers are affected by this issue. Found by OSS-Fuzz. Fix     developed by Tomas Mraz. Fixed in OpenSSL 3.0.13 (Affected since 3.0.0). (CVE-2023-6237)

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