CVE-2021-40400

An out-of-bounds read vulnerability exists in the RS-274X aperture macro outline primitive functionality of Gerbv 2.7.0 and dev (commit b5f1eacd) and the forked version of Gerbv (commit d7f42a9a). A specially-crafted Gerber file can lead to information disclosure. An attacker can provide a malicious file to trigger this vulnerability.
