Description

TiEmu 2.08 and prior contains a stack-based buffer overflow vulnerability that allows attackers to execute arbitrary code by exploiting inadequate boundary checks on user-supplied input. Attackers can trigger the overflow through command-line arguments passed to the application, leveraging ROP gadgets to bypass protections and execute shellcode in the application context.
