Comment (by steven-michaud):

 I'll attach a patch to Alpine 2.25 that fixes this bug. I tried to neaten
 up the logic, and alter it as little as possible. Here's pseudo-code that
 shows how it makes `ssl_validate_cert()` work:

 {{{
 for (each field in `cert`'s "subject name") {
   if (field matches `host`) {
     return NIL (success);
   }
 }
 for (each of `cert`'s `subject_alt_name` extensions) {
   if (`subject_alt_name` matches `host`) {
     return NIL (success);
   }
 }
 return error;
 }}}
