**Name of the Vulnerable Software and Affected Versions** Mupen64Plus versions through 2.6.0 **Description** A security issue has been identified in Mupen64Plus. The `write is viewer` function within the `src/device/cart/is viewer.c` file is susceptible to an integer overflow. This issue can be initiated remotely and is considered to have high complexity with difficult exploitability. The exploit has been publicly disclosed. The vendor was informed of this disclosure but did not respond. **Recommendations** Update Mupen64Plus to a version newer than 2.6.0. As a temporary workaround, consider restricting access to the `write is viewer` function until a patch is available.
