CVE-2010-0645 in Chrome
Summary
by MITRE
Multiple integer overflows in factory.cc in Google V8 before r3560, as used in Google Chrome before 4.0.249.89, allow remote attackers to execute arbitrary code in the Chrome sandbox via crafted use of JavaScript arrays.

The vulnerability identified as CVE-2010-0645 represents a critical security flaw in Google V8 JavaScript engine that was widely exploited in web browsers. This issue affected Google Chrome versions prior to 4.0.249.89 and stemmed from integer overflow conditions within the factory.cc component of the V8 engine. The vulnerability specifically targeted the handling of JavaScript arrays, creating a pathway for remote code execution within the Chrome sandbox environment. Integer overflows occur when arithmetic operations produce results that exceed the maximum value that can be stored in the allocated memory space, often leading to unpredictable behavior and potential exploitation opportunities.
The technical implementation of this vulnerability involved manipulating JavaScript array operations to trigger integer overflow conditions in the V8 engine's memory management system. When attackers crafted malicious JavaScript code that created arrays with carefully calculated dimensions, the engine would overflow integer values during internal calculations, potentially corrupting memory structures. This memory corruption could then be leveraged to overwrite critical program data or execute arbitrary code with the privileges of the browser process. The vulnerability was particularly dangerous because it occurred within the Chrome sandbox, which is designed to isolate browser processes from the underlying operating system, yet the integer overflow allowed attackers to bypass these protective measures.
The operational impact of CVE-2010-0645 was significant as it enabled attackers to perform remote code execution on vulnerable systems without requiring user interaction or specific privileges. This vulnerability could be exploited through malicious websites, making it particularly dangerous for web-based attacks. The integer overflow conditions were triggered during array creation and manipulation operations, allowing attackers to craft JavaScript payloads that would cause memory corruption and potentially lead to full system compromise. The vulnerability affected not only the browser itself but also the underlying operating system, as successful exploitation could elevate privileges and bypass traditional security controls.
Mitigation strategies for CVE-2010-0645 focused primarily on updating to patched versions of Google Chrome and the V8 engine. Google released version 4.0.249.89 which included fixes for the integer overflow conditions in factory.cc. Organizations should have implemented immediate patch management procedures to update all affected systems. Additional protective measures included browser hardening configurations, sandboxing enhancements, and network-level protections such as web application firewalls. The vulnerability aligns with CWE-190, which specifically addresses integer overflow conditions, and represents a classic example of how memory safety issues in interpreted languages can lead to severe security consequences. This vulnerability also demonstrated the importance of robust input validation and proper memory management in JavaScript engines, as the issue was resolved through improved integer bounds checking and overflow detection mechanisms in the V8 engine's array handling code.
