OVERVIEW:

       A number of security vulnerabilities have been corrected in the latest
       version of Google Chrome.


IMPACT:

       The vendor has provided the following information regarding these
       vulnerabilities:

       "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.

       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." [1]


MITIGATION:

       Google Chromes stable version 2.0.172.31 has been released to correct
       these vulnerabilities. It is available for download from the vendor's
       website. [2]
