CVE-2023-35702 is a high-severity vulnerability affecting GTKWave 3.3.115, specifically within its FST LEB128 varint functionality. Multiple stack-based buffer overflows in the fstReaderVarint32 function allow an attacker to achieve arbitrary code execution by tricking a victim into opening a specially crafted .fst file. The CVSS score of 7.8 (High) indicates a local attack vector with low complexity, but requiring user interaction, and leading to high impacts on confidentiality, integrity, and availability. While no public exploits, Metasploit modules, or Nuclei templates are currently available, and there is minimal community discussion or media coverage, the potential for arbitrary code execution warrants attention.
