Technical details

A classic buffer overflow vulnerability exists in the Rainbow Six Multiplayer engine's handling of the 'nick' command. The application fails to properly validate the length of the nickname string provided by a remote client before copying it into a fixed-size memory buffer. An attacker can exploit this by sending an excessively long nickname, leading to memory corruption. This can result in a denial of service (application crash) or potentially the execution of arbitrary code with the privileges of the game server process. The attack is reachable over the network without prior authentication.
