high Nessus Plugin ID 328649

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

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

 An information disclosure vulnerability in dnsmasq allows remote attackers to bypass source checks via a crafted DNS packet with RFC 7871 client subnet information.(CVE-2026-4893)

 A heap-based out-of-bounds write vulnerability in the DHCPv6 implementation of dnsmasq allows local attackers to execute arbitrary code with root privileges via a crafted DHCPv6 packet.(CVE-2026-4892)

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

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