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.

The RuntimeHelpers.InitializeArray method in metadata/icall.c in Mono, when Moonlight 2.x before 2.4.1 or 3.x before 3.99.3 is used, does not properly restrict data types, which allows remote attackers to modify internal read-only data structures, and cause a denial of service (plugin crash) or corrupt the internal state of the security manager, via a crafted media file, as demonstrated by modifying a C# struct. El método RuntimeHelpers.InitializeArray de metadata/icall.c de Mono, si Moonlight 2.x anterior a 2.4.1 o 3.x anterior a 3.99.3 es utilizado, no restringe apropiadamente los tipos de datos, lo que permite a atacantes remotos modificar las estructuras de datos de sólo lectura internas, y provocar una denegación de servicio (caída o cuelgue del plugin) o coromper el estado interno del gestor de seguridad, a través de un fichero multimedia modificado, como se ha demostrado modificando una struct C#. • http://lists.opensuse.org/opensuse-updates/2011-04/msg00024.html http://openwall.com/lists/oss-security/2011/04/06/14 http://secunia.com/advisories/44002 http://secunia.com/advisories/44076 http://www.mono-project.com/Vulnerabilities http://www.securityfocus.com/bid/47208 http://www.vupen.com/english/advisories/2011/0904 https://bugzilla.novell.com/show_bug.cgi?id=667077 https://exchange.xforce.ibmcloud.com/vulnerabilities/66624 https://github.com/mono/mono/commit/035c8587c0d8d307 • CWE-264: Permissions, Privileges, and Access Controls •
