GHSA-XJ96-63GP-2GMR Pillow: Heap out-of-bounds write in `ImageFilter.RankFilter` via integer overflow in `ImagingExpand`

Summary Pillow's public rank-filter API can trigger a native heap out-of-bounds write when given a very large odd filter size. Minimal public API trigger: python from PIL import Image, ImageFilter im = Image.new"L", 3, 3, 128 im.filterImageFilter.MedianFilter4294967295 ImageFilter.RankFilter.filt...

BIT-PILLOW-2026-59197 Pillow: Heap out-of-bounds write in Pillow `ImageFilter.RankFilter` via integer overflow in `ImagingExpand`

Pillow is a Python imaging library. Prior to 12.3.0, Pillow's public rank-filter API can trigger a native heap out-of-bounds write when given a very large odd filter size because ImageFilter.RankFilter.filter calls image.expandsize // 2, size // 2 before rank-filter size validation and...

Out-of-bounds Write

Overview Affected versions of this package are vulnerable to Out-of-bounds Write in the ImageFilter.RankFilter process when a very large odd filter size is provided, leading to unchecked signed integer arithmetic in ImagingExpand. An attacker can cause a heap out-of-bounds write by supplying...

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...

python-pillow: Pillow: Denial of Service via crafted PCF font data

A flaw was found in Pillow, a Python imaging library. A remote attacker could exploit this vulnerability by providing specially crafted PCF font data. This data, when processed, can lead to excessive memory allocation because the library does not properly check for decompression bombs. The primar...

CVE-2026-14454 Imager versions before 1.033 for Perl treat unsigned EXIF IFD entry counts as signed

Imager versions before 1.033 for Perl treat unsigned EXIF IFD entry counts as signed. Imager mishandled large EXIF IFD entry count values, treating them as negative numbers. This could lead to an attempt to allocate a block nearly the size of the address space, which fails and kills the process. ...
