Debian DLA-1965-1 : nfs-utils security update

critical Nessus Plugin ID 130071

Synopsis

The remote Debian host is missing a security update.

Description

In the nfs-utils package, providing support files for Network File System (NFS) including the rpc.statd daemon, the directory /var/lib/nfs is owned by statd:nogroup. This directory contains files owned and managed by root. If statd is compromised, it can therefore trick processes running with root privileges into creating/overwriting files anywhere on the system.

For Debian 8 'Jessie', this problem has been fixed in version 1.2.8-9+deb8u1.

We recommend that you upgrade your nfs-utils packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected nfs-common, and nfs-kernel-server packages.
