Pillow: Heap out-of-bounds write Image.paste / Image.crop via signed coordinate overflow...

CVE-2026-59199

A flaw was found in Pillow, a Python imaging library. A remote attacker could exploit a vulnerability in the library's image processing functions, specifically when handling image coordinates near certain limits. This flaw, a native heap out-of-bounds write, could lead to a denial of service DoS,...

PYSEC-2026-3451

Pillow is a Python imaging library. Prior to 12.3.0, Pillow public image coordinate APIs can trigger a native heap out-of-bounds write when given coordinates near the signed 32-bit integer limits in Image.paste, Image.crop, or Image.alphacomposite. This issue is fixed in version 12.3.0...

PT-2026-38488

A bounds check was performed in floating points before a cast to the index passed to an unchecked access function. This checked considered NaN cases improperly, causing them to succeed the check instead of failing it. The floating point coordinate is under caller control by passing a selected...
