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

    Issue summary: An application trying to decrypt CMS messages encrypted using

    password based encryption can trigger an out-of-bounds read and write.Impact summary: This out-of-bounds
    read may trigger a crash which leads to Denial of Service for an application. The out-of-bounds write can
    cause a memory corruption which can have various consequences including a Denial of Service or Execution
    of attacker-supplied code.Although the consequences of a successful exploit of this vulnerabilitycould be
    severe, the probability that the attacker would be able to perform it is low. Besides, password based
    (PWRI) encryption support in CMS messages is very rarely used. For that reason the issue was assessed
    asModerate severity according to our Security Policy.



    The FIPS modules in 3.5, 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected by this issue, as the CMS
    implementation is outside the OpenSSL FIPS module boundary.(CVE-2025-9230)

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

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