More than likely.
Most kits come with a set amount of priming sugar for bottling, in your case, 5oz. This is their estimation on how much sugar you will need to carbonate your batch IF you hit all of your volumes right...
In the future, I would check how much priming sugar I need with an online calculator, and confirm how much you ACTUALLY need, versus how much was in the kit.

So, if you bottled 4.5gal (assuming here) of beer with 5oz of priming sugar, your beers would carbonate to about 2.75vol of CO2. Which, isn't too terrible, but they are going to foam up a little extra when you open them. Get them very cold, and this should help with over-foaming when you pour one of the bottles.
It could be a few other things too...I guess I can touch on a few more.
1. Did you mix the sugar well with ALL the beer before you bottled it? If not, you could have some bottles that are more carbed than others. Did you open just one bottle, or more than one?
2. It could be an infection. Are there off flavors at all?
I would bet if its just slight, you used just a bit too much priming sugar for the volume of beer you bottled...
