28 Nov 2018 — In FreeBSD before 11.2-STABLE(r340854) and 11.2-RELEASE-p5, the NFS server lacks a bounds check in the READDIRPLUS NFS request. Unprivileged remote users with access to the NFS server can cause a resource exhaustion by forcing the server to allocate an arbitrarily large memory allocation. En FreeBSD, en versiones anteriores a la 11.2-STABLE(r340854) y la 11.2-RELEASE-p5, el servidor NFS carece de una comprobación de límites en la petición NFS READDIRPLUS.

CVE-2016-6559 – The BSD libc library's link_ntoa() function may be vulnerable to a classic buffer overflow
https://notcve.org/view.php?id=CVE-2016-6559
13 Jul 2018 — Improper bounds checking of the obuf variable in the link_ntoa() function in linkaddr.c of the BSD libc library may allow an attacker to read or write from memory. The full impact and severity depends on the method of exploit and how the library is used by applications. According to analysis by FreeBSD developers, it is very unlikely that applications exist that utilize link_ntoa() in an exploitable manner, and the CERT/CC is not aware of any proof of concept. A blog post describes the functionality of link... • http://www.securitytracker.com/id/1037398 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
