Moonlight-common-c is vulnerable to buffer overflow starting in commit f57bd745b4cbed577ea654fad4701bea4d38b44c. A malicious game streaming server could exploit a buffer overflow vulnerability to crash a moonlight client. Achieving RCE is possible but unlikely, due to stack canaries in use by modern compiler toolchains. The published binaries for official clients Qt, Android, iOS/tvOS, and Embedded are built with stack canaries, but some unofficial clients may not use stack canaries. This vulnerability takes place after the pairing process, so it requires the client to be tricked into pairing to a malicious host. It is not possible to perform using a man-in-the-middle due to public key pinning that takes place during the pairing process. The bug was addressed in commit b2497a3918a6d79808d9fd0c04734786e70d5954."}, {"lang": "es", "value": "Moonlight-common-c contiene el c\u00f3digo principal del cliente GameStream compartido entre los clientes Moonlight. Moonlight-common-c es vulnerable al desbordamiento del b\u00fafer a partir de el commit f57bd745b4cbed577ea654fad4701bea4d38b44c. Un servidor de transmisi\u00f3n de juegos malicioso podr\u00eda aprovechar una vulnerabilidad de desbordamiento del b\u00fafer para bloquear un cliente Moonlight. Lograr RCE es posible, pero poco probable, debido a los canarios de pila que utilizan las cadenas de herramientas de compilaci\u00f3n modernas. Los binarios publicados para los clientes oficiales Qt, Android, iOS/tvOS y Embedded est\u00e1n creados con canarios de pila, pero es posible que algunos clientes no oficiales no utilicen canarios de pila. Esta vulnerabilidad se produce despu\u00e9s del proceso de emparejamiento, por lo que requiere que se enga\u00f1e al cliente para que se empareje con un host malicioso. No es posible realizar utilizando un intermediario debido a la fijaci\u00f3n de clave p\u00fablica que tiene lugar durante el proceso de emparejamiento.
