Google has patched Chrome and Chrome OS, protecting users from denial of service (DoS) and hijacking, among other things.

The updates for the search engine’s web browser and operating system also include performance tweaks, as well as better support for those running Apple iOS on the recently released iPhone 6.

One critical Chrome OS bug allowed remote code execution out of the sandbox which isolates files for analysis before they are launched on the main system, and the system was also prone to a version of the Shellshock vulnerability that afflicted Linux, Unix and Mac.

Users will now be able to transfer files from Android to Chrome OS using the Media Transfer Protocol (MTP) via the Files app, and touch screen accessibility has also been improved on Chrome OS.

169 security fixes and 113 "relative minor" bug fixes were applied to Chrome on Windows, Mac and Linux, including flaws that allowed attackers to bypass permissions, leak information and remotely execute code.

iOS users will now be allowed to download and open files from Google Drive, the search engine’s cloud storage service.
