The stable build of Google Chrome has updated, introducing seven security patches to the browser. Version 4.1.249.1059 for Windows incorporates four high-priority security fixes and three medium-priority ones.

The high-priority fixes, introduced Tuesday, correct type confusion errors with forums, memory corruption in the V8 JavaScript engine bindings, cross-site scripting vulnerabilities on the Chrome downloads page, and HTTP request errors. The first two corrections earned user "kuzzcc" $500 each in Google Chrome's vulnerability discovery rewards program.

The medium-priority errors involved local file reference through developer tools, cross-site scripting in chrome://net-internals, and the discovery that some external pages could load with the rights privileges of the New Tab page.

Meanwhile, Mozilla has been moving forward with its Firefox 3.6.4 beta 1 for Windows, Mac, and Linux.
