Synopsis

The remote openSUSE host is missing one or more security updates.

Description

The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:20281-1 advisory.

Update to version 1.7.0 (bsc#1257128).

Security issues fixed:

- CVE-2025-64435: logic flaw in the virt-controller can lead to incorrect status updates and potentially causing a DoS (bsc#1253189).
- CVE-2024-45310: kubevirt vendored github.com/opencontainers/runc/libcontainer/utils: runc can be tricked into creating empty files/directories on host (bsc#1257422).
- CVE-2025-22872: incorrectly interpreted tags can cause content to be placed wrong scope during DOM construction (bsc#1241772).
- CVE-2025-64432: fail to correctly validate certain fields in the client TLS certificate may allow an attacker to bypass existing RBAC controls (bsc#1253181).
- CVE-2025-64433: improper symlink handling can allow to read arbitrary files (bsc#1253185).
- CVE-2025-64434: compromising virt-handler instance can lead to impersonate virt-api and execute privileged operations (bsc#1253186).
- CVE-2025-64437: mishandling of symlinks can lead to compromising the CIA (bsc#1253194).
- CVE-2025-64324: a logic bug that allows an attacker to read and write arbitrary files owned by more privileged users (bsc#1253748).

Other updates and bugfixes:

- Upstream now uses stateless firmware for CoCo VMs.

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

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