CVE-2025-59732

Status: DeferredHigh (8.7)—

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 td->uncompressed_data is allocated in decode_block based on the precise height and width of the image, so the "rounded-up" multiple of 8 in the copy loop can exceed the buffer bounds, and the write block starting at [2] can corrupt following heap memory.

We recommend upgrading to version 8.0 or beyond.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

OpenEXR con DWAA/DWAB: buffer overflow en decodificación requiere archivo malformado (UI:P, interacción usuario). Overflow de heap puede ejecutar código o corromper datos adyacentes.

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
