The libraries that are FIPS certified reads this flag to decide if they have to operate in FIPS mode. Firefox's nss bundled code by default reads this flag. Firefox is not one of FIPS certified libraries and should not be reading this flag. A bug has been filed against Ubuntu firefox package here - https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1843044 Actual results: On a FIPS enabled system. firefox crashes while starting up. An strace showed that it was repeatedly reading the flag before the crash. Expected results: Firefox and its associated nss bundled code are not FIPS certified and hence should not be reading the /proc/sys/crypto/fips_enabled flag. I propose to disable reading that flag.
