SUSE CVE-2026-112404

Pillow is a Python imaging library. From 8.1.0 until 13.0.0, Pillow's TIFF tile and RGBA decode paths can read beyond row data produced by libtiff. In decodeTile and the RGBA unpacker path, when Pillow and libtiff interpret duplicated PhotometricInterpretation or BitsPerSample tags differently,...

SUSE CVE-2026-112897

Pillow is a Python imaging library. From 5.3.0 until 13.0.0, Pillow can return uninitialized memory as pixels when libtiff performs a short decode of JPEG-compressed or Group 4 fax TIFF data. The decodeStrip and decodeTile buffers can be larger than the bytes written by libtiff, but Pillow conver...

SUSE CVE-2026-112393

Pillow is a Python imaging library. From 2.0.0 until 13.0.0, Pillow has a heap buffer overflow and stale-heap disclosure in tiffWriteProc when saving compressed TIFF data through libtiff to a target without a usable fileno, such as BytesIO. The callback sizes its allocation from the prior buffer...

SUSE CVE-2026-112396

Pillow is a Python imaging library. From 11.3.0 until 13.0.0, Pillow has a heap use-after-free when libtiff rejects a tag while encoding TIFF data to an in-memory buffer. When an application saves attacker-influenced TIFF tags to BytesIO, libtiff can reject a tag during encoding in...

Pillow: TIFF encoder ColorMap plane-size mismatch causes a heap out-of-bounds read

Summary A small attacker-supplied TIFF can be opened and loaded normally, then reach an out-of-bounds read when an application saves it back to TIFF with retained metadata. The fixed reproducer is a 1×1, 16-bit grayscale, PackBits-compressed TIFF containing tag 320 ColorMap with 768 SHORT values:...
