Technical particulars on the zero-day vulnerability
A zero-day is a vulnerability in software program or {hardware} that’s sometimes unknown to the seller and for which no patch or different repair is out there. The zero-day vulnerability which is being mounted right here is known as CVE-2024-7971: a kind confusion in V8 in Google Chrome which allowed a distant attacker to use heap corruption through a crafted HTML web page.
JavaScript makes use of dynamic typing which implies the kind of a variable is decided and up to date at runtime, versus being set at compile-time in a statically typed language.
V8 is the JavaScript engine that Chrome makes use of and has been a big supply of safety issues.
Heap corruption happens when a program modifies the contents of a reminiscence location outdoors of the reminiscence allotted to this system.

So, an attacker must persuade a goal to open a specifically crafted HTML file, which often means visiting a web site. This may trigger the unpatched browser to simply accept an surprising worth for a variable that can trigger an overflow of the reserved reminiscence location. The attacker is ready to abuse that overflow for their very own malicious functions.
