Pillow affected by out-of-bounds write when loading PSD images

CVE-2026-25990 / GHSA-cfh3-3jmp-rvhc

More information

Details

Impact

An out-of-bounds write may be triggered when loading a specially crafted PSD image. Pillow >= 10.3.0 users are affected.

Patches

Pillow 12.1.1 will be released shortly with a fix for this.

Workarounds

Image.open() has a formats parameter that can be used to prevent PSD images from being opened.

References

Pillow 12.1.1 will add release notes at https://pillow.readthedocs.io/en/stable/releasenotes/index.html

FITS GZIP decompression bomb in Pillow

CVE-2026-40192 / GHSA-whj4-6x5x-4v2j

More information

Details

Impact

Pillow did not limit the amount of GZIP-compressed data read when decoding a FITS image, making it vulnerable to decompression bomb attacks. A specially crafted FITS file could cause unbounded memory consumption, leading to denial of service (OOM crash or severe performance degradation).

Patches

The amount of data read is now limited to the necessary amount.
Fixed in Pillow 12.2.0 (PR #​9521).

Workarounds

Avoid Pillow >= 10.3.0, < 12.2.0
Only open specific image formats, excluding FITS.
