+Subject: [PATCH] Fixes #401.
+
+JPEG-2000 (JPC) Encoder:
+- Added some missing range checking on several coding parameters
+  (e.g., precint width/height and codeblock width/height).
+
+CVE: CVE-2025-8836
+Upstream-Status: Backport [https://github.com/jasper-software/jasper/commit/79185d32d7a444abae441935b20ae4676b3513d4]
