Technical Details for CVE-2024-4671
Vulnerability Analysis
The vulnerability results from a use-after-free condition in the visual components of Google Chrome, where memory is not properly managed during HTML processing. This flaw permits remote attackers to elevate privileges and escape sandbox constraints.
Root Cause
Improper handling of memory pointers during visual rendering allows memory to be reused incorrectly, leading to a use-after-free state.
Attack Vector
This vulnerability can be exploited over a network by a remote attacker through the delivery of a specially crafted HTML page.
// Example exploitation code (sanitized)
void triggerUseAfterFree() {
VisualComponent *vc = new VisualComponent();
delete vc;
// At this point, accessing `vc` leads to use-after-free
vc->render(); // Potential exploitation point
}
