Criticism of GOST

Basic
it is impossible to determine the cryptographic strength of an algorithm without knowing the substitution table in advance;
implementations of the algorithm from different manufacturers may use different
ability to provide weak replacement tables containing
potential possibility (no prohibition in the standard) of using tables
