      "value": "Moonlight-common-c contains the core GameStream client code shared between Moonlight clients. Moonlight-common-c is vulnerable to buffer overflow starting in commit 50c0a51b10ecc5b3415ea78c21d96d679e2288f9 due to unmitigated usage of unsafe C functions and improper bounds checking. A malicious game streaming server could exploit a buffer overflow vulnerability to crash a moonlight client, or achieve remote code execution (RCE) on the client (with insufficient exploit mitigations or if mitigations can be bypassed). The bug was addressed in commit 02b7742f4d19631024bd766bd2bb76715780004e."

Moonlight-common-c es vulnerable al desbordamiento del b\u00fafer a partir de el commit 50c0a51b10ecc5b3415ea78c21d96d679e2288f9 debido al uso absoluto de funciones C inseguras y a una verificaci\u00f3n de los l\u00edmites inadecuada. Un servidor de transmisi\u00f3n de juegos malicioso podr\u00eda aprovechar una vulnerabilidad de desbordamiento del b\u00fafer para bloquear un cliente de luz nocturna o lograr la ejecuci\u00f3n remota de c\u00f3digo (RCE) en el cliente (con mitigaciones de explotaci\u00f3n insuficientes o si se pueden evitar las mitigaciones).
