What it is

🚨 Memory safety bugs are lurking in Firefox 102, potentially leading to arbitrary code execution! 🔥 Think of it like a restaurant where the chef accidentally mixes up the ingredients, creating dishes that could poison unsuspecting diners.

An attacker could exploit these memory safety bugs to execute any code they choose on a victim's system, which could lead to total control over the user's device. This is absolutely devastating; imagine someone else running the show while you sip your coffee!
