DEBIAN-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...

DEBIAN-CVE-2026-112892

Pillow is a Python imaging library. From 4.1.0 until 13.0.0, Pillow's MSP RLE decoder can expand a small file into an unbounded in-memory buffer. The decoder writes run-length output to BytesIO without limiting expansion to the declared image size. An attacker can supply a crafted MSP image to an...

CVE-2026-112892

The Pillow Python imaging library (versions 4.1.0 to 13.0.0 ) contains a vulnerability in the MSP RLE decoder where a small file can expand into an unbounded in-memory buffer . The root cause is that the decoder writes run-length output to BytesIO without limiting expansion to the declared image ...

CVE-2026-112892 Pillow: MSP RLE decoder expands a tiny file into unbounded memory

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 ...

Python 3.5 scan_eol() Buffer Over-Read Vulnerability

Python 3.5 suffers from a vulnerability caused by the behavior of the scaneol function. When called, the function gets a line from the buffer of a BytesIO object by searching for a newline character starting at the position in the buffer. However, if the position is set to a value that is larger...
