TiEmu 3.03-nogdb+dfsg-3 contains a buffer overflow vulnerability in the ROM parameter handling that allows local attackers to crash the application or execute arbitrary code. Attackers can supply an oversized ROM parameter to the tiemu command-line interface to overflow the stack buffer and overwrite the instruction pointer with malicious addresses.
