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.
The kfreebsd-8 kernel in the oldstable distribution (squeeze) does not
enable the new NFS implementation. The Linux kernel is not affected
by this vulnerability.
