CVE-2023-42801

Estado: ModificadaAlta (7.6)—

Moonlight-common-c contains the core GameStream client code shared between Moonlight clients. 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.

Leer descripción completaMostrar menos

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.

Moonlight-common-c es vulnerable al desbordamiento del búfer a partir de el commit f57bd745b4cbed577ea654fad4701bea4d38b44c. Un servidor de transmisión de juegos malicioso podría aprovechar una vulnerabilidad de desbordamiento del búfer 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 compilación modernas. Los binarios publicados para los clientes oficiales Qt, Android, iOS/tvOS y Embedded están creados con canarios de pila, pero es posible que algunos clientes no oficiales no utilicen canarios de pila. Esta vulnerabilidad se produce después del proceso de emparejamiento, por lo que requiere que se engañe al cliente para que se empareje con un host malicioso. No es posible realizar utilizando un intermediario debido a la fijación de clave pública que tiene lugar durante el proceso de emparejamiento. El error se solucionó en el commit b2497a3918a6d79808d9fd0c04734786e70d5954."
