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

    A flaw was found in the RPM Package Manager (RPM). A local user could be affected by a heap buffer
    overflow vulnerability when processing a specially crafted NDB database file. This issue arises from an
    error in how RPM handles certain calculations during file parsing, leading to an incorrect memory
    allocation. An attacker could leverage this to cause a denial of service, making the system
    unavailable.(CVE-2026-44605)

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

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