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

    ping in iputils before 20250602 allows a denial of service (application error in adaptive ping mode or
    incorrect data collection) via a crafted ICMP Echo Reply packet, because a zero timestamp can lead to
    large intermediate values that have an integer overflow when squared during statistics calculations. NOTE:
    this issue exists because of an incomplete fix for CVE-2025-47268 (that fix was only about timestamp
    calculations, and it did not account for a specific scenario where the original timestamp in the ICMP
    payload is zero).(CVE-2025-48964)

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

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