Echo: pillow: security update to 12.3.0

high Tenable Self-Hosted Container Security Plugin ID 465688

Description

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

 - Pillow is a Python imaging library. From 8.2.0 through 12.2.0, src/libImaging/Jpeg2KDecode.c accumulates
 total_component_width 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 trigger out-of-memory
 failures during decoding. This issue is fixed in version 12.3.0. (CVE-2026-59204)

Solution

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