the typical buffer overflow would have been caught by OpenBSD's protective malloc.

I don’t think the vulnerability was in malloced memory, it was some buffer on the stack. I’ve actually patched OpenSSL to stop heart bleed as an excersice and iirc the fix was in fact just preventing a typical buffer overflow.

Seems like that commenter is also saying that it would’ve been caught as a regular buffer overflow bug?
