FreeBSD : FreeBSD -- Multiple issues in the bhyve hypervisor (eb5c615d-a173-11ef-9a62-002590c1f29c)

medium Nessus Plugin ID 210917

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the eb5c615d-a173-11ef-9a62-002590c1f29c advisory.

Several vulnerabilities were found in the bhyve hypervisor's device models.
The NVMe driver function nvme_opc_get_log_page is vulnerable to a buffer over- read from a guest-controlled value. (CVE-2024-51562) The virtio_vq_recordon function is subject to a time-of-check to time-of-use (TOCTOU) race condition. (CVE-2024-51563) A guest can trigger an infinite loop in the hda audio driver.
(CVE-2024-51564) The hda driver is vulnerable to a buffer over-read from a guest-controlled value. (CVE-2024-51565) The NVMe driver queue processing is vulernable to guest-induced infinite loops. (CVE-2024-51566) Malicious guest virtual machines may be able to perform a denial of service (DoS) of the bhyve host, and may read memory within the bhyve process that they should not be able to access.

Tenable has extracted the preceding description block directly from the FreeBSD 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 packages.
