NVD Description

Note: Versions mentioned in the description apply only to the upstream python311-Pillow package and not the python311-Pillow package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

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.
