14 DAY TRIAL // Google promoted its Chrome browser to a new stable revision, 37.0.2062.94, which integrates a total of 50 security fixes, and one of the bug hunters received a $30,000 / €22,750 reward for disclosing a combination of vulnerabilities that led to remote code execution outside the sandbox.
The bug hunter, identified as lokihardt@asrt, found glitches in V8, Chrome’s JavaScript engine, the Inter-process Communication (IPC), the data synchronization component and extensions, which combined provided a potential attacker the possibility to run arbitrary code on the targeted machine.
Apart from this reward, Google also paid $13,000 / €9,850 to other researchers, for use-after-free vulnerabilities in DOM, SVG and bindings, spoofing of the extension permission dialog, uninitialized memory read in WebGL and Web Audio, and for an issue related to extension debugging.
An additional $8,000 / €6,065 was paid by the company to researchers that worked with the Chrome development team on making sure that some security bugs never made it to the stable version of the web browser.
Google’s own security team also discovered glitches based on internal audits, fuzzing and other types of activities. Address Sanitizer tool, a memory error detection utility, was used for the discovery of many of the security bugs fixed in this revision.
