Description
yTree 1.94-1.1 contains a stack-based buffer overflow vulnerability that allows local attackers to execute arbitrary code by supplying an excessively long argument to the application. Attackers can craft a malicious command-line argument containing shellcode and a return address to overwrite the stack and execute code in the application context.
