CVE-2023-35969

Estado: ModificadaAlta (7.8)—

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.

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).
