It wouldn't go up to infinity. Let's do take five labeled A through E and they all have 1000 armor by default. We'll run through all of them at once, update, and run through them again. ⋮
 * 1) A through E have 1000 armor, so  gives a self-buff of 120 armor to each individual, and an aura buff of 120 armor to all the rest.
 * 2) * Note how the self-buff doesn't compound on itself, it's just a flat 12% of the base before the bonus.
 * 3) So A through E each have one self-buff and four aura buffs, all of which increase armor, and we know the self-buffs aren't counted when calculating the 12%.  We also know that aura buffs don't stack, so our total armor on everyone is 1000120120 1240.
 * 4) Let's be generous and say that the aura bonus counts for calculating the 12%, so our  are considered to be at 1120 for those purposes.  Recalculate!
 * 5) A through E have 1120 armor, so  gives a self-buff of 134.4 armor to each individual, and an aura buff of 134.4 armor to all the rest.
 * 6) So A through E each have one self-buff and four aura buffs, all of which increase armor, and we know the self-buffs aren't counted when calculating the 12%.  We also know that aura buffs don't stack, so our total armor on everyone is 1000134.4134.4 1268.8.
 * 7) For purposes of calculating the 12%, our  are now considered to be at 1134.4 armor.  Recalculate!

And so on. Notice how the armor base went from 1000 to 1120 to 1134.4; the additional bonus got much smaller each time; in fact, it was only 12% as large each time. Something12%12%12%... is called a geometric sequence. Adding them up is called a geometric series, and in the case of the common ratio "12%" (or 0.12), the sum of adding all of those factors infinitely comes out to 13. 63 % of the original number (in the case of this example, that original number is 1000).

tl;dr No, it's not infinite, because math.
