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.

Multiple OS command injection vulnerabilities exist in the decompression functionality of GTKWave 3.3.115. A specially crafted wave file can lead to arbitrary command execution. A victim would need to open a malicious file to trigger these vulnerabilities.This vulnerability concerns decompression in the `vcd2lxt` utility.

Multiple OS command injection vulnerabilities exist in the decompression functionality of GTKWave 3.3.115. A specially crafted wave file can lead to arbitrary command execution. A victim would need to open a malicious file to trigger these vulnerabilities.This vulnerability concerns decompression in the `vcd2lxt2` utility.

Multiple OS command injection vulnerabilities exist in the decompression functionality of GTKWave 3.3.115. A specially crafted wave file can lead to arbitrary command execution. A victim would need to open a malicious file to trigger these vulnerabilities.This vulnerability concerns decompression in the `vcd2vzt` utility.

Multiple OS command injection vulnerabilities exist in the decompression functionality of GTKWave 3.3.115. A specially crafted wave file can lead to arbitrary command execution. A victim would need to open a malicious file to trigger these vulnerabilities.This vulnerability concerns decompression in `vcd_recorder_main`.
