Technical Details for CVE-2024-4761

Vulnerability Analysis

The vulnerability involves an out of bounds write in the V8 component of Google Chrome, which could allow memory corruption and potentially provide a vector for remote code execution.

Root Cause

Improper bounds checking in the array handling mechanisms of the V8 engine, leading to unintended data writes.

Attack Vector

Attackers can exploit this via a network vector by tricking users into accessing a specially crafted HTML page that executes malicious scripts.

javascript

// Example exploitation code (sanitized)
<script>
  var buffer = new ArrayBuffer(64);
  var intView = new Int32Array(buffer);
  
  // Incorrect bounds handling
  intView[-1] = 31337; // Out of bounds write example
</script>

Detection Methods for CVE-2024-4761

Indicators of Compromise

Unexpected application crashes
Anomalous outbound traffic
Memory corruption alerts

Detection Strategies

Monitor for scripts that perform out of bounds operations in the V8 engine, particularly in network-received payloads. Use heuristic scanning to detect atypical memory usage patterns.

Monitoring Recommendations

Deploy script scanning solutions with behavioral threat detection capabilities. Utilize network monitoring to identify unusual HTML or JavaScript traffic patterns.

How to Mitigate CVE-2024-4761

Immediate Actions Required

Update Google Chrome to version 124.0.6367.207 or later
Implement strict Content Security Policy (CSP) rules
Disable JavaScript on untrusted sites

Patch Information

Google has provided a patch in version 124.0.6367.207 and later, addressing the bounds checking vulnerabilities in the V8 engine.

Workarounds

Restrict JavaScript execution and employ security features like sandboxing to limit the impact of potential exploitation attempts.

bash

# Configuration example
echo "@pref set pref.global.sandbox true" >> /etc/chrome.conf
