 Bugfix
-   * Fix a bug present in multiple example programs where running the program
-     from the shell without any command line argument results argv[1] being
-     accessed. The above was fixed for the following: pem2der.c, cert_req.c, 
-     cert_app.c, cert_write.c, req_app.c, crl_app.c, dh_genprime.c, key_app.c,
-     gen_key.c, key_app_writer.c, ssl_client2.c, ssl_server2.c, 
-     ssl_mail_client.c.
+   * Fix behavior of certain sample programs which could, when run with no
+     arguments, access uninitialized memory in some cases. Fixes #6700 (which
+     was found by TrustInSoft Analyzer during REDOCS'22) and #1120.
