The s_mp_div function in lib/freebl/mpi/mpi.c in Mozilla Network Security
Services (NSS) before 3.21, as used in Mozilla Firefox before 44.0,
improperly divides numbers, which might make it easier for remote attackers
to defeat cryptographic protection mechanisms by leveraging use of the (1)
mp_div or (2) mp_exptmod function.
