CVE-2025-59731
Heap-buffer-overflow write in FFmpeg EXR dwa_uncompress
Résumé
Heap-buffer-overflow write in FFmpeg EXR dwa_uncompress
Description d'origine
La description telle que publiée par la source (souvent en anglais).
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 rle_raw_size from the input file at [0], we decompress and decode into the buffer td->rle_raw_data of size rle_raw_size at [1], and then at [2] we will access entries in this buffer up to (td->xsize - 1) * (td->ysize - 1) + rle_raw_size / 2, which may exceed rle_raw_size.
We recommend upgrading to version 8.0 or beyond.
