FreeBSD : FreeBSD -- Multiple vulnerabilities in libnv (8d1f9adf-6b4f-11ef-9a62-002590c1f29c)

critical Nessus Plugin ID 206692

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 8d1f9adf-6b4f-11ef-9a62-002590c1f29c advisory.

 CVE-2024-45287 is a vulnerability that affects both the kernel and userland. A malicious value of size in a structure of packed libnv can cause an integer overflow, leading to the allocation of a smaller buffer than required for the parsed data.
 CVE-2024-45288 is a vulnerability that affects both the kernel and userland. A missing null-termination character in the last element of an nvlist array string can lead to writing outside the allocated buffer.
 It is possible for an attacker to overwrite portions of memory (in userland or the kernel) as the allocated buffer might be smaller than the data received from a malicious process. This vulnerability could result in privilege escalation or cause a system panic.

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.
