So keep your decoders up to date. I don't know how old is "too old" here...
Too old versions would mean versions before June/July of 2017. Corresponding patches where:
FFmpeg
avcodec/h264_cabac: Fix CABAC+8x8dct in 4:4:4
avcodec/h264_mb: Fix 8x8dct in lossless for new versions of x264
Libav
h264_cabac: Fix CABAC+8x8dct in 4:4:4
h264dec: fix Lossless Decoding (Profile 244) for 8x8 Intra Prediction

With old versions of FFmpeg/Libav you can have problems decoding lossless or 4:4:4+CABAC streams encoded with new x264.
