What it is

⚠️ This buffer overflow vulnerability in Firefox and SeaMonkey could let attackers execute arbitrary code, all thanks to some sneaky exception timing! Think of it like a busy restaurant where a waiter keeps bringing the wrong orders because they can't keep track of all the dishes coming in — eventually, the kitchen gets overwhelmed and serves up something completely unintended! An attacker could take advantage of this flaw to run any code they wish on a victim's system, potentially leading to a complete takeover of the browser. This could result in stolen data, unauthorized access to sensitive information, or worse. Yikes!
