  - 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)

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