CVE-2021-40391

An out-of-bounds write vulnerability exists in the drill format T-code tool
number functionality of Gerbv 2.7.0, dev (commit b5f1eacd), and the forked
version of Gerbv (commit 71493260). A specially-crafted drill file can lead to
code execution. An attacker can provide a malicious file to trigger this
vulnerability.
