When decoding an OpenEXR file that uses DWAA or DWAB compression, the specified raw length of run-length-encoded data is not checked when using it to calculate the output data. We read rlerawsize from the input file at [0], we decompress and decode into the buffer td->rlerawdata of size rlerawsize at [1], and then at [2] we will access entries in this buffer up to (td->xsize - 1) * (td->ysize - 1) + rlerawsize / 2, which may exceed rlerawsize. We recommend upgrading to version 8.0 or beyond.
