Description Sandipan Roy 2022-04-18 04:43:23 UTC

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.
