1) Resource management error (CVE-ID: CVE-2014-1453)
CWE-ID: CWE-399 - Resource Management Errors
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
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.
