Multiple integer overflow vulnerabilities exist in the VZT facgeometry parsing 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 integer overflow when allocating the `msb` array.
