Out-of-bounds Write

Overview Affected versions of this package are vulnerable to Out-of-bounds Write in the dwauncompress function when decoding OpenEXR files with DWAA or DWAB compression. An attacker can cause arbitrary memory writes by crafting files with mismatched channel types and counts, leading to pointer...

CVE-2025-59733

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...

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...

CVE-2025-59731

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 a...

CVE-2025-59732

When decoding an OpenEXR file that uses DWAA or DWAB compression, there's an implicit assumption that the height and width are divisible by 8. If the height or width of the image is not divisible by 8, the copy loops at 0 and 1 will continue to write until the next multiple of 8. The buffer...

CVE-2025-59733

FFmpeg/OpenEXR dwa_uncompress vulnerability (CVE-2025-59733): OpenEXR DWAA/DWAB decoding incorrectly assumes all channels share the same pixel type/size and that four channels map to B, G, R, A. If the main color channels are 4-byte and there are duplicate/unknown channels with 2-byte EXR_HALF, c...

CVE-2025-59732

FFmpeg/OpenEXR vulnerability CVE-2025-59732 arises when decoding DWAA/DWAB-compressed images: if height/width are not multiples of 8, copy loops extend beyond the allocated uncompressed_data, because the buffer is sized to exact dimensions while the loop uses the rounded-up 8-aligned size. This c...
