Description

The vulnerability allows a remote #AU# to perform service disruption.

The NFS server (nfsserver) in FreeBSD 8.3 through 10.0 does not acquire locks in the proper order when converting a directory file handle to a vnode, which allows remote authenticated users to cause a denial of service (deadlock) via vectors involving a thread that uses the correct locking order.


Remediation

Install update from vendor's website.
