Summary
Details

Multiple improper array index validation vulnerabilities exist in the fstReaderIterBlocks2 tdelta functionality of GTKWave 3.3.115. A specially crafted .fst file can lead to arbitrary code execution. A victim would need to open a malicious file to trigger these vulnerabilities.This vulnerability concerns the tdelta indexing when signal_lens is 1.
