Google has released an update for Chrome 15 which addresses a high-risk vulnerability.
However, because Google Chrome uses a native sandbox that prevents attackers from executing malicious code, the severity of the bug was downgraded.
The vulnerability was discovered by Mozilla security engineer Christian Holler, who was paid US$1,000 through the Chromium Vulnerability Rewards Programs for reporting it. The new Google Chrome 15.0.874.121 for Windows, Mac, Linux, also addresses a non-security issue that causes SVG elements loaded within iframes to ignore specified dimensions.
This is actually a regression bug introduced by recent code modifications. Other fixes contained in this release deal with the browser's behavior on Chrome OS, Google's cloud-oriented operating system, and include changes to the default NAT traversal policy used by the Chromoting remote access feature, the downloads folder display, the login process, and the GPU blacklist.
Corporate network administrators can deploy it by using the Google Update for enterprise policy.
