Package        : nfs-utils
Version        : 1.2.8-9+deb8u1
CVE ID         : CVE-2019-3689
Debian Bug     : 940848


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.
