CVE-2025-59731: Ffmpeg

Medium severity, CVSS 6.9. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Ffmpeg Ffmpeg: from 7.1.1, before 8.0 (fixed in 8.0)
