Extensions can no longer use inline scripts, such as <script> ... </script>. Instead, extensions must use out-of-line scripts loaded from within their package, such as <script src="foo.js"></script>.

Extensions can no longer use eval(). Note: If you’re using eval to parse JSON today, we suggest using JSON.parse instead.

Extensions can load plug-ins, such as SWF files, only from within their package or from a whitelist of HTTPS hosts.

improve the securityThese defenses are extremely effective: adopting one of the recommended CSPs would prevent 96% (49 out of 51) of the core extension vulnerabilities we found. manifest_versionmanifest_versionmanifest_versionextension documentationmailing list

The Future of JavaScript – take a peek today!

Lexical scoping. Now "let" is the new "var" – traditional "var" declarations are complemented with "let" and "const". Both are properly block-scoped bindings, eliminating a common source of errors and weird behaviour. Function declarations are now officially allowed in local scope as well, and also obey lexical scoping. (Note: Lexical scoping is only available in ES strict mode.)

Collections. Efficient maps and sets will make your life easier. Any value can be used as a key or element, including objects. No surprises, no more need to abuse objects as dictionaries. (Caveat: Iteration over collections is not yet specified.)

Weak maps. A special kind of map for which the garbage collector determines when a key is no longer reachable, so that the key-value pair can be removed from the map automatically. This goes a long way towards avoiding memory leaks in long-lived tables and relieves the developer from worrying about stale entries.

Expanding the Chromium Security Rewards Program

Thursday, February 9, 2012

first announceda big hit

High-severity Chromium OS security bugs are now in scope. Chromium OS includes much more than just the Chromium browser, so we’re rewarding security bugs across the whole system, as long as they are high severity and present when “developer mode” is switched off. Examples of issues that may generate a reward could include (but are not limited to):

Renderer sandbox escapes via Linux kernel bugs.
Memory corruptions or cross-origin issues inside the Pepper Flash plug-in.
Serious cross-origin or memory corruption issues in default-installed apps, extensions or plug-ins.
Violations of the verified boot path.
Web- or network-reachable vulnerabilities in system libraries, daemons or drivers.

Chromium bug tracker

We may elect to issue “bonuses” ranging from $500 to $1000 if a bug reporter takes on fixing the bug they have found themselves. For eligibility, this process involves working with the Chromium community to produce a peer reviewed patch. These bonuses are granted on top of the base reward, which typically runs between $500 and $3133.70.

The base reward for a well-reported and significant cross-origin bug (for example a so-called UXSS or “Universal XSS”) is now $2000.
