EulerOS Virtualization 2.12.1 : libvirt (EulerOS-SA-2026-1470)

medium Nessus Plugin ID 302725

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

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

 A flaw was discovered in libvirt in the XML file processing. More specifically, the parsing of user provided XML files was performed before the ACL checks. A malicious user with limited permissions could exploit this flaw by submitting a specially crafted XML file, causing libvirt to allocate too much memory on the host. The excessive memory consumption could lead to a libvirt process crash on the host, resulting in a denial-of-service condition.(CVE-2025-12748)

 A flaw was found in libvirt. External inactive snapshots for shut-down VMs are incorrectly created as world-readable, making it possible for unprivileged users to inspect the guest OS contents. This results in an information disclosure vulnerability.(CVE-2025-13193)

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

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

Solution

Update the affected libvirt packages.
