Google Chrome’s Stable channel has been updated to version 2.0.172.31 to fix two security issues in WebKit.CVE-2009-1690 Memory corruption
A memory corruption issue exists in WebKit’s handling of recursion in certain DOM event handlers. Visiting a maliciously crafted website may lead to a tab crash or arbitrary code execution in the Google Chrome sandbox. This update addresses the issue through improved memory management.

Severity: High. An attacker might be able to run arbitrary code within the Google Chrome sandbox.

Mitigations:
A victim would need to visit a page under an attacker’s control.
Any code that an attacker might be able to run inside the renderer process would be inside the sandbox. 
CVE-2009-1718 Drag and drop information leak
An issue exists in WebKit’s handling of drag events. This may lead to the disclosure of sensitive information when content is dragged over a maliciously crafted web page. This update addresses the issue through improved handling of drag events.

Severity: Medium. An attacker might be able to read data belonging to another web site, if a user can be convinced to select and drag data on an attacker-controlled site.
