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...

CVE-2026-112897

The Pillow Python imaging library (versions 5.3.0 through 13.0.0 ) is vulnerable to an issue where it can return uninitialized memory as pixels. This occurs when libtiff performs a short decode of JPEG-compressed or Group 4 fax TIFF data. Specifically, the _decodeStrip and _decodeTile buffers may...

CVE-2026-112897 Pillow: TiffDecode returns uninitialized memory as pixels for short JPEG strips

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...

CVE-2026-112896 Pillow: TIFF encoder ColorMap plane-size mismatch causes a heap out-of-bounds read

Pillow is a Python imaging library. Prior to 13.0.0, Pillow's TIFF encoder can read beyond a ColorMap buffer when retained TIFF metadata has a plane size inconsistent with BitsPerSample. A small TIFF can be opened normally and then retain a crafted ColorMap that is reused when the image is saved...

CVE-2026-112896

The Pillow Python imaging library (versions prior to 13.0.0 ) contains a vulnerability in its TIFF encoder . An out-of-bounds read can occur when retained TIFF metadata contains a plane size inconsistent with BitsPerSample , causing the encoder to read beyond a ColorMap buffer . An attacker can p...

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,...

CVE-2026-112404

The Pillow Python imaging library (versions 8.1.0 through 13.0.0 ) contains an out-of-bounds read in the TiffDecode.c tile and RGBA decode paths. The vulnerability occurs because the library fails to verify that required input rows fit within the data produced by libtiff when certain tags like Ph...

CVE-2026-112404 Pillow: OOB read in TiffDecode.c tile and RGBA paths leaks heap memory into pixels

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,...

DEBIAN-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...

CVE-2026-112396

The Pillow Python imaging library (versions 11.3.0 through 13.0.0 ) is vulnerable to a heap use-after-free flaw when encoding TIFF data to an in-memory buffer. The issue arises because libtiff may reject an attacker-influenced tag during encoding in ImagingLibTiffEncode . In this error path, the ...

CVE-2026-112396 Pillow: Heap use-after-free when encoding TIFF to an in-memory buffer

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...
