Name of the Vulnerable Software and Affected Versions GTKWave version 3.3.115

Description Multiple stack-based buffer overflow vulnerabilities exist in the FST LEB128 varint functionality. 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 issue concerns the fstReaderVarint32WithSkip function.

Recommendations For GTKWave version 3.3.115, consider disabling the fstReaderVarint32WithSkip function as a temporary workaround until a patch is available. Restrict access to .fst files from untrusted sources to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
