Description Hubert Kario 2016-11-23 17:46:23 UTC 
Description of problem:
When configuring crypto-policy to enable or disable algorithms, configuration files that don't end with two consecutive new-line characters are ignored by NSS.

Version-Release number of selected component (if applicable):
nss-util-3.27.1-2.el6.

How reproducible:
Always

Steps to Reproduce:
cat > /etc/pki/nss-legacy/nss-rhel6.config <<EOF
library=
name=Policy
NSS=flags=policyOnly,moduleDB
config="allow=md5"
EOF'

Connect to server that uses MD5 certificates

Actual results:
Connection is aborted

Expected results:
Connection succeeds, server certificate is validated 

Additional info:
Marking as medium as this kind of newline sensitivity is uncommon and unexpected, making silent misconfigurations likely.
