Google on Wednesday pushed out a new version of its Chrome browser to users, a release that fixes four security bugs, including two critical vulnerabilities.
Only one of the bugs fixed in Chrome 11.0.696.71 qualified for the company’s bug bounty program, a high-severity problem caused by a stale pointer. That vulnerability earned the researcher who reported it, Martin Barbella, a $1,000 reward. The vulnerabilities fixed in this release include:
-  Low CVE-2011-1801: Pop-up blocker bypass. Credit to Chamal De Silva.
- [$1000]  High CVE-2011-1804: Stale pointer in floats rendering. Credit to Martin Barbella.
-  Critical CVE-2011-1806: Memory corruption in GPU command buffer. Credit to Google Chrome Security Team (Cris Neckar).
-  Critical CVE-2011-1807: Out-of-bounds write in blob handling. Credit to Google Chrome Security Team (Inferno) and Kostya Serebryany of the Chromium development community.
Google has been on a quick release schedule for Chrome for some time now, and the company has been able to fix vulnerabilities and other problems very quickly. Google has released several new versions of Chrome in just the last month, fixing more than two dozen security vulnerabilities in the process. Mozilla officials have said that it plans to move Firefox to a similar release schedule soon, and that the next version of the browser will be the last major release of that kind.
