CVE-2010-3113 in Chrome
Summary
by MITRE
Google Chrome before 5.0.375.127, and webkitgtk before 1.2.5, does not properly handle SVG documents, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via unknown vectors related to state changes when using DeleteButtonController.

The vulnerability identified as CVE-2010-3113 represents a critical memory corruption issue affecting web browsers that utilize WebKit rendering engines. This flaw exists in Google Chrome versions prior to 5.0.375.127 and WebKitGTK versions before 1.2.5, where the browser fails to properly process Scalable Vector Graphics documents. The vulnerability specifically manifests when the DeleteButtonController component handles state changes within SVG content, creating conditions that can lead to unpredictable system behavior. The issue stems from inadequate input validation and memory management within the browser's SVG processing pipeline, particularly when dealing with complex state transitions in vector graphics elements.
The technical exploitation of this vulnerability occurs through maliciously crafted SVG documents that trigger improper memory handling within the DeleteButtonController module. When a browser encounters such malformed SVG content, the controller's state management mechanisms fail to properly handle the transition between different document states, leading to memory corruption. This memory corruption can manifest as heap corruption, stack overflow conditions, or other memory management failures that may result in browser crashes or potentially enable arbitrary code execution. The vulnerability's impact extends beyond simple denial of service since the memory corruption can be leveraged to execute malicious code in the context of the browser process, making it particularly dangerous for users who encounter compromised web content.
From an operational perspective, this vulnerability presents significant risks to organizations relying on affected browsers for web-based applications and services. The remote attack vector means that users can be compromised simply by visiting malicious websites or viewing compromised email attachments containing malicious SVG content. The vulnerability's potential for unspecified other impacts suggests that attackers may be able to exploit the memory corruption for privilege escalation or information disclosure attacks. This flaw directly impacts the browser's security model and can undermine the isolation between different web content types, potentially allowing attackers to bypass security boundaries that should protect the user's system from malicious web content.
The vulnerability aligns with CWE-121, which describes heap-based buffer overflow conditions, and represents a classic example of improper memory handling in web browser components. From an attack framework perspective, this vulnerability maps to several ATT&CK techniques including initial access through malicious web content and execution through memory corruption exploits. Organizations should prioritize patching affected systems and implementing additional security controls such as web application firewalls and content filtering solutions. Browser sandboxing and privilege separation mechanisms should be enabled to limit the potential impact of successful exploitation, while regular security updates and vulnerability assessments should be conducted to identify similar issues in other browser components and web technologies.
Mitigation strategies should include immediate patch deployment for all affected browser versions, implementation of SVG content filtering where possible, and enhanced monitoring for suspicious web traffic patterns. Network administrators should consider implementing web proxy filtering to block known malicious SVG content and establish incident response procedures for handling potential exploitation attempts. The vulnerability demonstrates the importance of thorough input validation and memory management in browser rendering engines, highlighting the need for continuous security testing and code review processes to identify similar issues before they can be exploited by malicious actors.
