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.

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)

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - 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)

The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2025-20100-1 advisory.

    - CVE-2025-13193: Fixed Information disclosure via world-readable VM snapshots (bsc#1253703)
    - CVE-2025-12748: Fixed Denial of service in XML parsing (bsc#1253278)

    Other fixes:

    - spec: Adjust dbus dependency (bsc#1253642)
    - qemu: Add support for Intel TDX (jsc#PED-9265)
