CVE-2023-36747

Estado: ModificadaAlta (7.8)—

Multiple heap-based buffer overflow vulnerabilities exist in the fstReaderIterBlocks2 fstWritex len functionality of GTKWave 3.3.115. A specially crafted .fst file can lead to memory corruption. A victim would need to open a malicious file to trigger these vulnerabilities.This vulnerability concerns the handling of `len` in `fstWritex` when `beg_time` does not match the start of the time table.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
