Summary
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.
