"According to the versions of the openssl111d packages installed, the EulerOS installation on the remote host is affected
by the following vulnerabilities :

    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)

Tenable has extracted the preceding description block directly from the EulerOS openssl111d security advisory.

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