Hi,

The following vulnerability was published for nfs-utils. Please note
that even thoug the description mentions the SUSE packages in Debian
similarly /var/lib/nfs is used.

CVE-2019-3689[0]:
| The nfs-utils package in SUSE Linux Enterprise Server 12 before and
| including version 1.3.0-34.18.1 and in SUSE Linux Enterprise Server 15
| before and including version 2.1.1-6.10.2 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 if fs.protected_symlinks is not set


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
