Chrome 40 Patches 62 Security Vulnerabilities, Pays Bounties Aplenty

Google released version 40 of the Chrome browser, patching 62 vulnerabilities, including close to two-dozen critical memory corruption flaws.

Google pushed out on Wednesday a new version of its Chrome browser (40.0.2214.91) and along with it paid out more than two dozen bounties, including 16 for memory corruption vulnerabilities.

In all, 62 security vulnerabilities were patched, 17 of those considered high severity bugs by Google.

Most of those high-severity vulnerabilities were memory corruption or use-after-free vulnerabilities in a number of Chrome components, including ICU, V8, FFmpeg and DOM.

A researcher credited as cloudfuzzer cashed in with $12,000 worth of bounties, including three critical bugs. Another reporter known as yangdingning was awarded $9,000 for his finds.

Here is the list of public vulnerabilities patched in Chrome 40.

This is the first Chrome release of the year; in November, Chrome 39 was released and included removal of support for the fallback to SSL 3.0, the target of the POODLE attack.
