Description

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.<br /> <br /> We read rle_raw_size from the input file at [0], we decompress and decode into the buffer td-&gt;rle_raw_data of size rle_raw_size at [1], and then at [2] we will access entries in this buffer up to (td-&gt;xsize - 1) * (td-&gt;ysize - 1) + rle_raw_size / 2, which may exceed rle_raw_size.<br /> <br /> <br /> <br /> <br /> We recommend upgrading to version 8.0 or beyond.
