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

    A flaw was found in GNU Coreutils. The sort utility's begfield() function is vulnerable to a heap buffer
    under-read. The program may access memory outside the allocated buffer if a user runs a crafted command
    using the traditional key format. A malicious input could lead to a crash or leak sensitive
    data.(CVE-2025-5278)

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

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