Debian Linux Security Advisory 2672-1 - Adam Nowacki discovered that the new FreeBSD NFS implementation processes a crafted READDIR request which instructs to operate a file system on a file node as if it were a directory node, leading to a kernel crash or potentially arbitrary code execution.

FreeBSD Security Advisory - When processing READDIR requests, the NFS server does not check that it is in fact operating on a directory node. An attacker can use a specially modified NFS client to submit a READDIR request on a file, causing the underlying filesystem to interpret that file as a directory.
