NVD Description

Note: Versions mentioned in the description apply only to the upstream m17n-lib package and not the m17n-lib package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

A flaw was found in m17n-lib. A user providing specially crafted text input can trigger a heap use-after-free condition during input-method state transitions. Under specific conditions, the library frees an internal input context object but subsequently attempts to write to that freed memory. This issue can cause applications relying on the library to crash, leading to a Denial of Service (DoS), or potentially allow arbitrary code execution.
