FreeBSD : FreeBSD -- Deadlock in the NFS server (6a384960-6007-11e6-a6c3-14dae9d210b8)
Medium Nessus Plugin ID 92898
SynopsisThe remote FreeBSD host is missing one or more security-related updates.
DescriptionThe kernel holds a lock over the source directory vnode while trying to convert the target directory file handle to a vnode, which needs to be returned with the lock held, too. This order may be in violation of normal lock order, which in conjunction with other threads that grab locks in the right order, constitutes a deadlock condition because no thread can proceed. Impact : An attacker on a trusted client could cause the NFS server become deadlocked, resulting in a denial of service.
SolutionUpdate the affected packages.
