GHSA-VJC4-5QP5-M44J Pillow JPEG2000 tiled decode retains a growing scratch buffer and can be used for denial of service

Summary src/libImaging/Jpeg2KDecode.c:853 accumulates totalcomponentwidth across every tile in a JPEG2000 image instead of recomputing it per tile. That accumulated value is then used in the tilebytes calculation at src/libImaging/Jpeg2KDecode.c:868, which can make the decoder grow state-buffer v...

UBUNTU-CVE-2026-59204

Pillow is a Python imaging library. From 8.2.0 through 12.2.0, src/libImaging/Jpeg2KDecode.c accumulates totalcomponentwidth across every tile in a JPEG2000 image instead of recomputing it per tile, allowing a crafted tiled JPEG2000 file to force substantially higher transient memory usage and...

PYSEC-2026-2843 OpenEXR Makes Use of Uninitialized Memory

Summary While fuzzing openexrexrcheckfuzzer, Valgrind reports a conditional branch depending on uninitialized data inside genericunpack. This indicates a use of uninitialized memory CWE-457. The issue is reproducible with the current OSS-Fuzz harness and a single-file PoC. Details Environment: -...

Name of the Vulnerable Software and Affected Versions Pillow versions 8.2.0 through 12.2.0 Description In the src/libImaging/Jpeg2KDecode.c file, the library accumulates total component width across every tile in a JPEG2000 image instead of recomputing it per tile. This behavior allows a speciall...

Astra Linux – Vulnerability in openimageio

There is a heap-based buffer overflow vulnerability in the tile decoding code of the TIFF image parser in OpenImageIO’s master-branch-9aeece7a and v2.3.19.0. A specially crafted TIFF file can lead to out-of-bounds memory corruption, which may result in arbitrary code execution. An attacker can...
