Name of the Vulnerable Software and Affected Versions EchoVNC Linux versions prior to 1.1.2

Description A stack-based buffer overflow issue exists in the CLogger::WriteFormated function, located in echoware/Logger.cpp. This allows remote echoServers to execute arbitrary code by sending a large group or user list, which can be described as a "very crowded echoServer" attack.

Recommendations For EchoVNC Linux versions prior to 1.1.2, update to version 1.1.2 or later to resolve the issue. As a temporary workaround, consider restricting the size of group or user lists received from remote echoServers to prevent exploitation.
