i2d_RSAPublicKey retval ignored in multiple callsites
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 (moved).
