Multiple out-of-bounds write vulnerabilities exist in the VZT vzt_rd_get_facname decompression functionality of GTKWave 3.3.115. A specially crafted .vzt file can lead to arbitrary code execution. A victim would need to open a malicious file to trigger these vulnerabilities.This vulnerability concerns the out-of-bounds write perfomed by the prefix copy loop.
