Chrome Buffer Overlow Vulnerability - "SaveAs" Function

Reported by, Sep 5 2008

Issue description

SVRT - Bkis have just discovered vulnerability in Google Chrome
and would like to inform you with this. Here comes the report:


- Type of Issue: Buffer Overflow.

- Affected Software: Google Chrome	

- Exploitation Environment: Google Chrome (Language: Vietnamese) on Windows

- Impact: Remote code execution

- Description: 
The vulnerability is caused due to a boundary error when handling the
“SaveAs” function. On saving a malicious page with an overly long title
(<title> tag in HTML), the program causes a stack-based overflow and makes
it possible for attackers to execute arbitrary code on users’ systems.

- How an attacker could exploit the issue : 
To exploit the Vulnerability, a hacker might construct a specially crafted
Web page, which contains malicious code. He then tricks users into visiting
his Website and convinces them to save this Page. Right after that, the
code would be executed, giving him the privilege to make use of the
affected system.

- Exploitation code: Proof of Concept: Crash (Attached to this document).

- Researcher: AnhLD – SVRT member.
