Description Bob Relyea 2011-10-18 17:13:42 UTC 
Description of problem:

The lab has identified a potential issue in the DRBG, where NIST has been more strict in the past. We may need to create a patch to fix this DRBG deficiency.

This bug is a place holder until more specifics are known.

Testing:

This patch is FIPS related. It requires running a set of builtin tests at POST time and when we reseed. I don't believe there is a way to inject a failure of these tests from outside, so they can only be 'tested' by inspection.

There are elements of the tests that can be detected using the FIPS test tool (used for algorithm testing). I'll supply some instructions on how to do that.

The only other testing is regression testing. Any FIPS smoke tests that generate keys with NSS should be sufficient. (even starting the browser in FIPS mode and connecting to an SSL website).

Elio, go ahead and build with this patch.

Thanks Ales. Here's the test I promised. It turns out the full fipstest.c doesn't build standalone, but I pulled out a simple test to see if this change has been made. Here's what the test looks like in the failure and success conditions:

bobs-laptop(109) cc -o test rngtest.c `pkg-config --cflags --libs nss` -lfreebl
bobs-laptop(109) test
Failed: DRBG initialized without enough entropy
bobs-laptop(110) setenv USE_64 1
bobs-laptop(111) usebuild nss-3-13
bobs-laptop(112) test
Success: DRGB properly failed to initialize without enough entropy.

rngtest.c will be attached in my next post.
