The vulnerability of the dwa_uncompress() function in the OpenEXR File Decoder component of the FFmpeg multimedia library allows a malicious actor to execute arbitrary code.

The vulnerability of the dwauncompress function in the OpenEXR File Decoder component of the FFmpeg multimedia library lies in the fact that the operation’s output goes beyond the buffer boundaries in memory. Exploiting this vulnerability could allow a remote attacker to execute arbitrary code...

CVE-2025-59733 Heap-buffer-overflow write in FFmpeg EXR dwa_uncompress

When decoding an OpenEXR file that uses DWAA or DWAB compression, there's an implicit assumption that all image channels have the same pixel type and size, and that if there are four channels, the first four are "B", "G", "R" and "A". The channel parsing code can be found in decodeheader. The...
