Need confirmation for some unpatched CVE

[the-Chain-Warden-thresh]

I'm cloning this repo to make some modifications to customize. However, I've noticed that some CVEs which were confirmed and fixed do not get patched in this repo. To enhance the availability of my project as far as possible, I will appreciate it if any of the CVE below do exist in this repo as well, so that I can fix these security issue myself by applying the corresponding patch.
Here are the CVEs I found in this repo unpatched, but get fixed:

CVE-2009-3720 in external/mit/expat/dist/lib/xmlparse.c's function static enum XML_Error doProlog(XML_Parser parser, const ENCODING *enc, const char *s, const char *end, int tok, const char *next, const char **nextPtr, XML_Bool haveMore), with patch here for your reference.

CVE-2016-6303 in crypto/external/bsd/openssl/dist/crypto/mdc2/mdc2dgst.c's function int MDC2_Update(MDC2_CTX *c, const unsigned char *in, size_t len), with patch here for your reference.

Hello, Thank you for putting together this list! However, I think this is only the tip of the iceberg. All in-tree software is at least 6 years old at this moment. Also, Minix needs more hardening to be suitable for production environments. So, I doubt that applying the patches you've provided would be helpful.

That is to say, all of the 8 CVE I've listed previously do impact this repo? Thanks a lot for your reply, then I'll apply the corresponding patch in order to start my own work as soon as possible. After you update the code openssl and other project mentioned above, I'll keep up with your newer version to continue my customization.
