Valve's Game Networking Sockets prior to version v1.2.0 improperly handles long unreliable segments in function SNP_ReceiveUnreliableSegment() when configured to support plain-text messages, leading to a Heap-Based Buffer Overflow and resulting in a memory corruption and possibly even a remote code execution. Game Networking Sockets de Valve versiones anteriores a v1.2.0, manejan de manera inapropiada segmentos largos y no confiables en la función SNP_ReceiveUnreliableSegment() cuando están configurados para admitir mensajes de texto plano, conllevando a un desbordamiento del búfer en la región heap de la memoria y resultando en una corrupción de la memoria y posiblemente incluso en una ejecución de código remota • https://github.com/ValveSoftware/GameNetworkingSockets/commit/e0c86dcb9139771db3db0cfdb1fb8bef0af19c43 https://research.checkpoint.com/2020/game-on-finding-vulnerabilities-in-valves-steam-sockets • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •
