PocketMine-MP invalid skin geometry JSON data leading to server crash
### Impact `pocketmine\entity\Skin` doesn't correctly handle errors produced by `adhocore/json-comment`, which throws `RuntimeException` rather than returning `false` as PocketMine-MP expects. This leads to a server crash if the skin geometry data is invalid for some reason (e.g. a syntax error). ### Patches c9626c610b8f6810c8c987559c9197b2a291f0bb ### Workarounds A plugin could handle `LoginPacket` and `PlayerSkinPacket` to verify the skin geometry data can be parsed correctly, so that the error condition in the core code is never reached. ### For more information If you have any questions or comments about this advisory: * Email us at [security@pmmp.io](mailto:security@example.com)
