  "details": "When decoding a frame for a SANM file (ANIM v0 variant), the decoded data can be larger than the buffer allocated for it.\n\nFrames encoded with codec 48 can specify their resolution (width x height). A buffer of appropriate size is allocated depending on the resolution.\n\nThis codec can encode the frame contents using a run-length encoding algorithm. There are no checks that the decoded frame fits in the allocated buffer, leading to a heap-buffer-overflow.\n\nprocess_frame_obj initializes the buffers based on the frame resolution:\n\n\n\nWe recommend upgrading to version 8.0 or beyond.",
