Yes, it does. It is, however, used for non-security purpose, and
this has nothing to do with FIPS.

Upgrade to nginx 1.11.2 or later. Starting with this version,
nginx will use internal MD5 implementation for hashing cache keys,
so using RHEL with FIPS enabled won't cause errors.

Note well that nginx 1.10.3 is obsolete for more than two years
now, so you may want to upgrade anyway. Latest nginx version is
1.17.1, latest stable is 1.16.0.
