VLAI?
Summary
Multiple heap-based buffer overflow vulnerabilities exist in the fstReaderIterBlocks2 VCDATA 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 decompression function `fastlz_decompress`.
Severity ?
