FINAL RESULTS:
data/tinygltf-2.5.0+dfsg/tiny_gltf.h:285:5: [2] (buffer) memcpy:
Does not check for buffer overflows when copying to destination (CWE-120).
Make sure destination can always hold the source data.
memcpy(binary_value_.data(), p, n);
data/tinygltf-2.5.0+dfsg/tiny_gltf.h:2088:12: [2] (buffer) char:
Statically-sized arrays can be improperly restricted, leading to potential
overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
functions that limit length, or ensure that the size is larger than the
maximum possible length.
unsigned char char_array_3[3];
