Multiple heap-based buffer overflow vulnerabilities exist in the fstReaderIterBlocks2 chain_table parsing 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 chain_table of `FST_BL_VCDATA` and `FST_BL_VCDATA_DYN_ALIAS` section types.
