According to the versions of the shim package 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)

    A remote code execution vulnerability was found in Shim. The Shim boot support trusts attacker-controlled     values when parsing an HTTP response. This flaw allows an attacker to craft a specific malicious HTTP     request, leading to a completely controlled out-of-bounds write primitive and complete system compromise.
    This flaw is only exploitable during the early boot phase, an attacker needs to perform a Man-in-the-     Middle or compromise the boot server to be able to exploit this vulnerability     successfully.(CVE-2023-40547)

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

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