Kerentanan Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') pada moonlight-stream moonlight-common-c, moonlight-stream moonlight +5 lainnya. Skor CVSS 3.1 8.8 (High) menurut NVD.

Deskripsi (NVD)

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.
