Vulnerability Title
Pillow: Heap out-of-bounds write in Pillow `ImageFilter.RankFilter` via integer overflow in `ImagingExpand`
Vulnerability Description
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.expand(size // 2, size // 2) before rank-filter size validation and ImagingExpand() computes output dimensions with unchecked signed int arithmetic. This issue is fixed in version 12.3.0.

Vulnerability Title
python-pillow Pillow 数字错误漏洞
Vulnerability Description
python-pillow Pillow是python-pillow的图像处理库。 python-pillow Pillow 12.3.0之前版本存在安全漏洞,该漏洞源于公共rank-filter API在给定非常大奇数滤镜大小时会触发原生堆越界写入,因为ImageFilter.RankFilter.filter()在rank-filter大小验证前调用image.expand(size // 2, size // 2),且ImagingExpand()使用未检查的有符号整数运算计算输出维度。
