What is buffer overflow, an old vulnerability that’s causing new problems? May 29, 2019 https://www.dailydot.com/layer8/buffer-overflow-whatsapp/
Yes, this is still a serious issue, it was actually the reason why I ended up on this forum. I knew that AV's back then weren't good enough to tackle buffer overflow exploits. But luckily Windows and popular apps like Chrome and Firefox have become hardened against these kind of attacks. But on smartphones, there is no third party defense tool, that's a big problem.
