CVE-2021-40402

Estado: ModificadaAlta (7.5)—

An out-of-bounds read vulnerability exists in the RS-274X aperture macro multiple outline primitives functionality of Gerbv 2.7.0 and dev (commit b5f1eacd), and Gerbv forked 2.7.1 and 2.8.0. A specially-crafted Gerber file can lead to information disclosure. An attacker can provide a malicious file to trigger this vulnerability.

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).
