CVSS: 7.6EPSS: 0%CPEs: 11EXPL: 2CVE-2023-42801 – Stack buffer overflow due to `strcpy` into fixed size buffer in `extractVersionQuadFromString`
https://notcve.org/view.php?id=CVE-2023-42801
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. • https://github.com/moonlight-stream/moonlight-common-c/blob/c1744de06938b5a5c8897a705be1bc6508dc7580/src/Misc.c#L82-L88 https://github.com/moonlight-stream/moonlight-common-c/commit/b2497a3918a6d79808d9fd0c04734786e70d5954 https://github.com/moonlight-stream/moonlight-common-c/commit/f57bd745b4cbed577ea654fad4701bea4d38b44c https://github.com/moonlight-stream/moonlight-common-c/security/advisories/GHSA-f3h8-j898-5h5v • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

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 24750d4b748fefa03d09fcfd6d45056faca354e0. Moonlight-common-c contiene el código principal del cliente GameStream compartido entre los clientes Moonlight. • https://github.com/moonlight-stream/moonlight-common-c/blob/2bb026c763fc18807d7e4a93f918054c488f84e1/src/RtspConnection.c#L796 https://github.com/moonlight-stream/moonlight-common-c/commit/24750d4b748fefa03d09fcfd6d45056faca354e0 https://github.com/moonlight-stream/moonlight-common-c/commit/50c0a51b10ecc5b3415ea78c21d96d679e2288f9 https://github.com/moonlight-stream/moonlight-common-c/security/advisories/GHSA-4927-23jw-rq62 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
