Description:Summary:
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.

Affected Software/OS:
kfreebsd-9 on Debian Linux

Solution:
For the stable distribution (wheezy), this problem has been fixed in
version 9.0-10+deb70.1.

For the testing distribution (jessie) and the unstable distribution
(sid), this problem has been fixed in version 9.0-11.

We recommend that you upgrade your kfreebsd-9 packages.
