CVE-2021-40402
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.32%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
