 Hello. Here follows a bug report by `Guido Vranken` received through the
 hackerone program.

 There are various places in the codebase where we don't check the retval
 of `i2d_RSA_PublicKey()` (or its callers). That function can fail in cases
 of OOM, and this is something we should be handling correctly. This is a
 similar case to #17686.
