CVE-2023-37578

Status: ModifiedHigh (7.8)—

Multiple use-after-free vulnerabilities exist in the VCD get_vartoken realloc functionality of GTKWave 3.3.115. A specially crafted .vcd file can lead to arbitrary code execution. A victim would need to open a malicious file to trigger these vulnerabilities.This vulnerability concerns the use-after-free when triggered via the vcd2lxt conversion utility.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
