The only thing really worse there is that the number of people who could audit the code is much smaller. That guy wrote a whole SSL library in assember, so he probably didn't just finish some assembler tutorial and decided this was a good first lil project.
Assember is usually just considered bad/dangerous by people who have no clue about it and consider it something magical. It's not. At least not significantly more dangerous than C, which is still the language the most fundamental components of everyday computing are based on.
