Echo: pillow: security update to 12.3.0

high Tenable Cloud Security Plugin ID 460736

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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.
 (CVE-2026-59197)

Solution

Update the pillow library and its related packages to version 12.3.0 or later.
